Research Spotlight


Paula P. Lemons, Professor (Biochemistry and Molecular Biology) & SEER Center Director
Interviewed by Andrea Horsman

Dr. Paula Lemons, PhD, is a Distinguished Scholar of the Owens Institute and Professor of Biochemistry and Molecular Biology. She received her B.S. at Southern Wesleyan University, her Ph.D. in Biochemistry at the University of Kentucky, and completed a postdoctoral fellowship at Duke University.

She has a passion to help students develop a deep understanding of science and the ability to solve real-world problems. During her postdoc years she transitioned to social and behavioral sciences research and became interested in problem solving and assessment. Her career was launched in biology education research, a relatively young interdisciplinary field, in which researchers investigate basic questions about learning, teaching, and the sociocultural context of undergraduate education.

Dr. Lemons is working on several research projects to transform STEM (Science, Technology, Engineering, and Math) education. We caught up with her and asked her to share some information about her STEM research and education at the University of Georgia.

How did you first get involved with STEM?

I received my PhD in biochemistry studying basic biology – how blood platelets secrete clotting factors. As a postdoc I transitioned to social and behavioral sciences research and I immediately became interested in problem solving and assessment. I had a passion to help students develop a deep understanding of science and the ability to solve real-world problems. I knew this focus had been lacking in my own education, and I wanted to make a difference.

During those postdoc years, I connected with colleagues with backgrounds in math and science education. They introduced me to research areas that required expert knowledge of science and social science methodologies, including classroom observations, clinical interviews, and qualitative data analysis. These collaborations launched my career in biology education research, a relatively young interdisciplinary field, in which researchers investigate basic questions about learning, teaching, and the sociocultural context of undergraduate education.

Tell me about your involvement in STEM research.

I teach biochemistry and I am conducting research in biochemistry learning. When I was a junior faculty member teaching biochemistry to sophomores and juniors here at UGA, I speculated that life science undergraduates’ early problem-solving skills may have long-term effects. That is, students who solve problems well as early undergrads experience success and that success feeds back to them in positive ways to propel persistence. In contrast, students who struggle to solve problems as early undergrads experience failures that feed back to discourage persistence. Part of my research is examining this idea – and a number of related ideas – in the context of biochemistry-specific problem solving.

Tell me about one of your research projects and why it is important.

In 2014 I was awarded a $900,000+ grant from National Science Foundation for a six year research project entitled, “Problem Solving Skills as Predictors of Success and Persistence in Biology.” This study aims to describe the biochemistry-specific problem-solving skills of life science students as they progress through their undergraduate course work at the University of Georgia. We have assessed the biochemistry problem-solving skills of hundreds of students in introductory biology, intermediate biochemistry, and advanced cell biology. This spring we will complete data collection for a cohort of 200 students who started their life science courses in fall 2016 or spring 2017. We collected cross-sectional data from hundreds of other students.

Through students’ written solutions and interview responses we have pinpointed challenging aspects of biochemistry problem solving. For example, the diagrams and models used for teaching often confuse students and contain implicit information that students miss. Also, students tend to describe biochemical phenomena superficially unless prompted to describe the underlying processes. Our research shows that explicit instruction can overcome these challenges.

This project also aims to identify the relationships among biochemistry problem-solving performance, affective and demographic variables. This summer, with our longitudinal data collection complete, we will use latent growth modeling to determine the changes in biochemistry-specific problem-solving performance over time for our sample of 200 students. Simultaneously, we will investigate the extent to which students’ self-efficacy and intrinsic motivation predict performance and the extent to which gender, URM status, and SES moderate these effects.

Conducting this research in biochemistry is important because biochemistry is one of the key courses taken by STEM majors, particularly pre-health professionals and biochemical or biomedical engineers. Biochemistry also offers an interesting context because students begin learning the basic concepts as early as high school through introductory biology and general chemistry courses, yet they typically do not deeply integrate their knowledge of biology and chemistry until college biochemistry.

Understanding learning challenges is important because surprisingly little is known about what makes science difficult. For biochemistry, we know it is abstract and that students must learn things they cannot see, but the particular stumbling blocks have not all been studied. Uncovering these challenges in detail provides a road map for improving instruction.

Understanding the relationships among problem solving, affective variables, and demographic variables will reveal how the experiences of different types of students vary and suggest ways to intervene to create sociocultural environments that make success and persistence attainable by all students.

What do you find most challenging about this research project?

The most challenging aspects of this research project have been developing assessments and collecting longitudinal data. We cannot directly measure what students know about biochemistry or their ability to apply their knowledge. Instead we depend on indirect measures – students’ responses to problem sets. We spent years developing assessments that passed the scrutiny of experts and the pilot testing of students. Even though we settled on assessment items that have provided rich and meaningful data, we know different assessments would reveal different aspects of student knowledge.

We have relentlessly worked with the UGA Office of Institutional Research and life science instructors to track and collect data from the students in our longitudinal cohort. We attempted to anticipate all paths and scenarios and to create strong incentives for students to complete all the data collection activities. We are pleased with our success, but it has challenged our wits and our patience.

Tell me about some of the people you’ve met through your research.

This project has opened up exciting collaborations at UGA and beyond. At UGA, I collaborate with Allan CohenHye-Jeong Choi, and Logan Fiorella all in the Department of Educational Psychology. Al, Hye-Jeong and I collaborate on the psychometric analyses of our problem-solving assessments. We also are using the biochemistry problem-solving data to test new methods like topic modeling. Topic modeling is a type of statistical modeling that allows for the discovery of “topics” in a collection of documents. We are looking for topics in student writing that may reveal new patterns in student thinking and problem-solving process.

Logan and I collaborate to understand the impact of evidence-based pedagogy on student learning in biochemistry. Logan brings expertise in investigating general learning mechanisms that may apply across educational contexts, and I bring expertise in the particular challenges of learning biochemistry. Together, we aim to test general learning mechanisms in disciplinary contexts that are persistently troublesome for students.

Outside of UGA, this work has led to an exciting collaboration with cognitive psychologist Mark McDaniel (Washington University) and chemistry education researcher Regina Frey (University of Utah) who are interested in individual differences in students learning tendencies that impact their performance in science courses. Specifically, they have shown that some students tend to learn by focusing on examples, while other students tend to learn by abstracting across examples. This tendency is distinct from intelligence or academic achievement. We will be using the biochemistry problem-solving assessments developed for this project to investigate the importance of individual learning tendencies in biochemistry.

Finally, this work has led to collaboration with Jennifer Loertscher at Seattle University. Jennifer specializes in biochemistry education and related research and led a national coalition to determine the most critical concepts in biochemistry education. Jennifer and I work to apply biochemistry education research to the classroom and assist faculty in using the research.

Tell me a little bit about the DeLTA research project.

I am the Principal Investigator for a $3 million NSF funded project called, “Transforming STEM Education at Research 1 University through Multi-Level Action Teams,” that was awarded in 2018.

This project involves over 100 faculty members in biology, chemistry, engineering, mathematics, physics and statistics working together to explore ways to better support, incentivize and reward effective, evidence-based STEM instruction and are creating, implementing and assessing active learning materials to help students better develop STEM knowledge and skills.

The project is formally known as DeLTA (Department and Leadership Teams for Action)and it is inherently a team effort. My co-principal investigators are Tessa Andrews (Genetics); Peggy Brickman (Plant Biology); and Erin Dolan (Biochemistry and Molecular biology). In addition, Associate Provost for Faculty Affairs Sarah Covert is also a co-principal investigator. We will be working with UGA senior administrators as well as department heads and other collaborators over a five year period on this project.

What do you think/hope will change regarding STEM over the next five years?

In the next five years, I hope more equity will be achieved in STEM education. Currently the majority of students who enter college intending to pursue a degree in STEM leave STEM. This problem disproportionately impacts women, underrepresented minorities, and students from lower socioeconomic status. Discipline-based education research has revealed a number of ways to address this problem. For example, pedagogies that actively engage students in learning can reduce failure and withdraw rates and improve learning gains. We also know that helping students build self-efficacy and science identity can improve their science achievement.

Individual courses and faculty play dramatic roles in maximizing student learning and supporting students to develop the affective characteristics that facilitate their success and persistence in STEM. Yet college faculty do not have training in pedagogy, and research faculty are not typically even evaluated on their teaching. Thus, I also hope that in the next five years, university departments and institutions will act to take undergraduate education more seriously. This will involve a combination of increased support, professional development, and accountability. We need ways to honor the expertise of faculty and help them learn how to roll that expertise into modern teaching approaches that match what we know about student learning.

Where can people go if they want to learn more about your other research?

I lead an interdisciplinary center on campus known as Scientists Engaged in Education Research, or SEER. The SEER Center includes faculty, postdocs, and graduate students across the University of Georgia who perform research in collegiate STEM education. As science and technology continue to expand their relevance for life in the 21st century, and as a scientifically educated workforce is under increasingly short supply, there is a pressing need for solutions to improving science education in the United States, and specifically to transform how science is taught and learned in colleges and universities. Research areas include basic and applied research grounded within STEM disciplines and informed by evidence-based theory in educational and social sciences. Research generated by participants in the Center catalyzes the transformation of STEM teaching and learning locally and nationally.

Dr. Jody Clay-Warner (Sociology)
Interviewed by Andrea Horsman

Dr. Jody Clay-Warner is a Meigs Professor of Sociology in the Franklin College of Arts and Sciences and has been at the University of Georgia since 1998. She received her Ph.D. in Sociology from Emory University, where she took comprehensive exams in both Social Psychology and Criminology. She also earned a Certificate in Women’s Studies. Dr. Clay-Warner is the co-director of the Laboratory for the Study of Social Interaction (LASSI) and the co-Director of the Violence Work Group at OIBR. In addition to many UGA committees, she is currently on the editorial board of Emotion Review and is on the Executive Board of the International Society for Research on Emotion, where she serves as treasurer of the Society.

Dr. Clay-Warner has been the recipient of many distinguished awards, including:

  • Women’s Leadership Fellow, University of Georgia, 2017-2018
  • Owen’s Creative Research Award for Distinguished Contributions to the Behavioral & Social Science, University of Georgia, 2017
  • Fellow, Society for Experimental Social Psychology, inducted 2009
  • Lifetime Achievement Teaching Award, American Society of Criminology, 2013

She loves to teach and this semester she is teaching a graduate seminar on Theories of Social Psychology. This class is fun for her because she gets to revisit theories she does not currently use in her own work and has a chance to catch up on recent developments in social psychological theory. Over the summer, she teaches Crime in Global Context as part of the Liverpool Study Abroad Program, which she co-directs.

Dr. Clay-Warner says the most exciting thing about sociology is that basic sociological principles can be used to help understand so many different parts of the social world. This is what allows her to study topics that are as disparate as ‘over reward’ and ‘criminal victimization.’  In addition, because sociologists are interested in a variety of substantive topics, there are many opportunities for interdisciplinary collaboration, which allows sociologists to benefit from and contribute to other fields of study, as well as have their research reach a broader audience.

The goal of Dr. Clay-Warner’s research is to understand responses to injustice. She addresses this issue through the lenses of social psychology and criminology.  As a social psychologist, she is interested in advancing basic science and engages in controlled laboratory experiments to examine how people respond cognitively, emotionally, and behaviorally when they are treated unfairly. As a criminologist, she applies this knowledge to understand the experience of criminal victimization, which she conceptualizes as an extreme form of injustice. At UGA she studies sexual violence and, more recently, human trafficking. She is also interested in understanding processes of revictimization. Specifically, she is interested in the explaining why having experienced a victimization event increases risk for a future victimization.

Currently Dr. Clay-Warner is devoted to two projects, one of which is focused on human trafficking in sub-Saharan Africa and one focused on sexual misconduct on college campuses. The first project is in collaboration with UGA researchers Dr. David Okech, Tamora Callands, and Nate Hansen, as well as researchers in the UK and in Africa. This project, funded by the U.S. Department of State Program to End Modern Slavery involves measuring the prevalence of child trafficking, as well as selecting and then evaluating prevention/intervention programs. She is particularly involved in the prevalence estimation work, which involves the application of novel sampling and statistical techniques for measuring hidden populations. The second project is in collaboration with her Sociology department colleague Justine Tinkler. They are designing a series of experiments to uncover the underlying social processes that affect men and women’s beliefs and attitudes about policies designed to counteract sexual harassment/misconduct, such as affirmative consent policies. This work builds upon Dr. Tinkler’s previous work on reactions to sexual harassment policy trainings and Dr. Clay-Warner’s work on reactions to injustice and on sexual violence.

Dr. Jody Clay-Warner joined the management team at OIBR as Associate Director in August. As Associate Director of OIBR, she oversees the faculty seed grant program, serves on the Grantsmanship Development Program Committee and the OIBR executive committee. Jody also represents OIBR in various capacities across the UGA campus and beyond.

She has been affiliated with OIBR since 2000, when she was in the Institute’s mentoring program as an assistant professor. When asked why she wanted to be the Associate Director, she said, “I know how valuable OIBR has been to me, and I want to help others benefit from the Institute. I’ve served in a number of administrative roles on campus and would like to apply the knowledge and skills I’ve acquired to advance the Institute’s mission.” Her thoughts on the future of the Institute, “OIBR’s future is bright. We are serving an increasing number of faculty across campus and are handling more grant activity than ever before. I expect this trend to continue, particularly as funding agencies become more aware of the value of interdisciplinary work.”

Dr. Clay-Warner is married to Lee Warner, who is an epidemiologist and branch chief at the Centers for Disease Control and Prevention. They met as freshmen at UNC-Chapel Hill and have been married for 27 years. Their son, Jared, is a senior at UNC-Chapel Hill, where he is double majoring in political science and communication studies. Their daughter, Avery, is a junior at UGA, double majoring in economics and criminal justice studies. That is four social science majors across two children, so clearly she did *something* right!

In her rare spare time, Dr. Clay-Warner enjoys hiking at the Botanical Gardens, pleasure reading, cooking and yoga. When asked if she had to pick another profession, what would it be? She replied, “If I were independently wealthy, I would choose to own a bookstore. I wouldn’t make any money, but I would be very happy.”

Dr. Gregory Strauss (Psychology)
Interviewed by Andrea Horsman

OIBR Fellow Dr. Gregory P. Strauss, is an Assistant Professor of Psychology and Neuroscience at UGA. He directs the Clinical Affective Neuroscience Lab (CAN) and Georgia Psychiatric Risk Evaluation Program (G-PREP). Dr. Strauss received his B.S. in Psychology from UGA (2002) and PhD in clinical psychology from UNLV after completing his clinical internship at the University of Illinois-Chicago (UIC), Department of Psychiatry (2008). He then completed a two year National Institute of Mental Health (NIMH) funded postdoctoral fellowship at the Maryland Psychiatric Research Center.

Dr. Strauss’ interest in psychology and neuroscience began when he was an undergraduate at UGA. He felt very fortunate to work in the laboratory of Dr. Paula Schwanenflugel a professor of Educational Psychology, who supervised his undergraduate honors thesis and made him believe he could pursue a career in research. He was also very fortunate to have worked in the laboratory of Dr. L. Stephen Miller who helped him develop an interest in what has become his passion and the focus of his research: examining the neural basis of schizophrenia using neuroscience based methods.

He was fortunate to have some very supportive mentors in his career in Drs. Daniel Allen, Martin Harrow, Jim Gold, and Will Carpenter. They helped him to see the importance of clinically oriented research and taught him to develop skills in neuroscience that are needed to answer questions about the mechanisms underlying schizophrenia. Most importantly, they imparted a scientific philosophy of doing careful research, taking the extra time to get the details right, making his research translational in nature, and caring deeply about helping the participants in his studies. Collaborators from a number of disciplines have also been integral in allowing him to adopt new methods and theoretical approaches, which has been critical for addressing a number of scientific questions that he could not have pursued alone.

His current research primarily examines the etiology, assessment, and treatment of negative symptoms in individuals diagnosed with schizophrenia and youth at clinical high-risk for psychosis.  Negative symptoms are reductions in behavior, emotion, and motivation that are common to many psychiatric and neurological disorders. There are five core negative symptom domains: avolition (reductions in the desire for and engagement in goal-directed activities), asociality (reductions in the engagement in and desire for social activity), anhedonia (reductions in the intensity and frequency of pleasurable activity), alogia (reductions in the quantity of speech), and blunted affect (reductions in the expression of emotion in face, voice, and body gestures). Once present, the five negative symptoms tend to be persistent and predict poor vocational and social outcomes, as well as low rates of recovery. Unfortunately, currently available pharmacological and psychosocial treatments have not proven efficacious for remediating negative symptoms. This is due in part to: 1) limited understanding of the mechanisms underlying negative symptoms and the fact that few clinical investigators are trained to take a cognitive or affective neuroscience approach to exploring pathophysiological mechanisms of negative symptom and 2) lack of conceptually up-to-date assessments of negative symptoms.

Much of Dr. Strauss’ work has focused on resolving these two issues. New tools were needed to enhance reliable and valid negative symptom assessment and he co-developed and validated a next-generation negative symptom rating scale for adults with schizophrenia in response to this initiative. The measure has now been translated into >20 languages and is becoming the gold-standard for use in clinical trials of negative symptoms in schizophrenia.

Dr. Strauss was recently awarded a $3 million grant from NIMH for his project entitled “Prodromal Inventory for Negative Symptoms (PINS): A Development and Validation Study.” This research will extend the measurement development efforts to youth who are at clinical high-risk for developing a psychotic disorder.

Psychotic disorders are serious and debilitating mental illnesses that incur substantial suffering for patients and present major challenges to our health care system. Given that few individuals achieve recovery after the onset of a psychotic disorder, there is increasing interest in the early identification and prevention of psychosis. Psychotic disorders are typically preceded by a prodromal (i.e., pre-illness) phase characterized by functional decline and subtle attenuated symptoms that progressively worsen over the course of several months to years.  This period is of interest both as a window for investigating processes involved in disease onset and as a potential point of intervention and prevention. State of the art clinical assessments are now available to identify a group of youth at “clinical high risk” (CHR) for developing a psychotic disorder based on attenuated positive symptom criteria. However, more than 75% of youth identified as CHR do not convert to full psychotic illness within two years and currently available risk prediction algorithms are thus not optimized for sensitivity and specificity. This application takes a novel approach to enhancing psychosis risk prediction by investigating negative symptoms. In the prodromal phase, negative symptoms (e.g., anhedonia, avolition, asociality) are highly prevalent (e.g., occurring in 82% of cases) and one of the earliest indicators of risk, typically appearing years before the emergence of attenuated positive symptoms. They are often the reason why CHR youth and their families seek initial contact with the treatment system, and one of the strongest predictors of conversion to psychosis. However, currently available risk calculators do not take negative symptoms into account. This study is a three site investigation, led by Dr. Strauss, which collects data at UGA, Northwestern University (Dr. Vijay Mittal), and Emory University (Dr. Elaine Walker). Several novel risk identification methods will be evaluated, including digital phenotyping (i.e., collecting data passively via the internal sensors of the phone such as geolocation, accelerometry, and speech), social media data, and a new negative symptom clinical rating scale. The goal is to derive a new set of risk prediction measures and algorithms that can detect risk for developing schizophrenia with a high degree of sensitivity and specificity. Dr. Strauss’ hope is that these measures can be widely available for use by the general public and clinicians to enhance the detection of psychosis, leading to an enhanced ability to prevent illness onset.

Since starting his work approximately 10 years ago, Dr. Strauss has been continually surprised by the need for mental health services throughout our country, as well as the pervasive lack of knowledge about the psychosis prodrome among mental health and educational professionals. Approximately 15% of the world’s population has occasional psychotic like experiences. Often these are transitory and do not cause distress, but occasionally they warrant clinical attention. The medical and educational fields have not focused on screening for these forms of mental illness, like they have others such as autism, ADHD, or suicidal ideation. Dr. Strauss feels that screening is necessary to enhance prevention efforts, and his hope is that his research is an important step in this direction. He adds that additional efforts are needed to disseminate this information to clinicians and educators who see young people on a daily basis and can help them to receive early monitoring and intervention services that could prevent the onset of psychotic disorders.

Dr. Strauss thinks turning neuroscience-based research results into clinically meaningful products is the biggest challenge facing his field. “We have been able to develop eloquent mathematical and neuroscience models of psychiatric symptoms in our research. But, translating these models to assessments and treatments that clinicians can meaningfully use is an important challenge. Our new R01 is a step in this direction,” he stated.

Helping young people at risk for developing psychosis and becoming part of their clinical care team has been highly rewarding for Dr. Strauss and the team of graduate students and employees that he supervises. “If we can help with the process of early identification, monitoring, and prevention for even a small number of people at risk for developing a psychotic disorder, we will have made a meaningful impact on the lives of people at a time when they need it most.”

“Our research relies on rapid translation of research done in basic neuroscience (i.e., animal models) to humans. This requires a team-based approach to science, and collaborators with expertise in multiple methods. Thus, my approach to science is one that is team-based and I strive to collaborate with others who have expertise in methods and conceptual frameworks that extend my own expertise, to allow more complex questions to be answered. This has included collaborating with other psychologists, neuroscientists, computer scientists, mathematicians, and engineers,” said Dr. Strauss.

In addition to the newly funded NIMH grant, Dr. Strauss has several other ongoing grants that focus on negative symptoms.

In an ongoing R21 from NIMH (R21 MH112925), Dr. Strauss is exploring mechanisms underlying anhedonia in adults with schizophrenia using novel mathematical approaches. This study uses the ecological momentary assessment method, which involves obtaining self-reports of emotion, symptoms, context etc., as well as ambulatory psychophysiology, in the context of everyday life. This data is submitted to computational models (e.g., network analysis, Markov chain analysis, Machine Learning) that evaluate whether anhedonia reflects an abnormality in the temporal dynamics of positive emotion (e.g., the trajectory leading up to or following a planned pleasurable activity). Results have potential to lead to an updated perspective on the nature of anhedonia, as well as its underlying mechanisms. This information will be useful for developing novel psychosocial treatments of negative symptoms that utilize cognitive therapy approaches to normalize the temporal dynamics of emotion in the context of everyday life using mobile cellular phone based interventions.

In a NARSAD Young Investigator grant funded by the Brain & Behavior Research Foundation, Dr. Strauss is exploring pathophysiological mechanisms underlying negative symptoms in youth at clinical high risk for a psychotic disorder. The study aims to determine whether abnormalities in cortico-striatal function lead to disruptions in a range of reward processes that contribute to avolition and anhedonia. Studies by Dr. Strauss and collaborators have found support for such a model in adults with schizophrenia, and this will reflect the first attempt to determine whether the model extends to youth at clinical high risk for schizophrenia. To evaluate this model, a range of behavioral, EEG, and computational modeling approaches will be used in a 2 year longitudinal study of youth at clinical high-risk for psychosis. Results have potential to inform new pharmacological targets for drug development by identifying neural mechanisms underlying negative symptoms in the prodromal period.

Over the next five years Dr. Strauss said his research will continue to explore novel mechanisms underlying negative symptoms in those diagnosed with schizophrenia and youth at clinical high-risk for developing psychosis. They have recently started adopting fMRI as a new method and plan to conduct a series of studies where they examine neural mechanisms that lead at-risk youth to develop a psychotic disorder versus other psychiatric diagnoses, such as mood and anxiety disorders.

The ultimate aim of Dr. Strauss’ research is to translate results obtained in the laboratory into enhanced risk monitoring and novel treatments of negative symptoms. Focusing on negative symptoms in the prodromal phase may reflect a novel means of tracking illness progression and even preventing the onset of psychotic disorders, which are the leading medical cause of functional disability in the United States.

Dr. Katherine Ehrlich (Psychology)
Interviewed by Andrea Horsman

OIBR Fellow Katherine Ehrlich, Assistant Professor with joint appointments in the Department of Psychology and the Center for Family Research, has been a very busy lady. This junior faculty member has recently been awarded three grants totaling close to $2.5 million dollars! All three research projects focus on how children’s social experiences shape their mental and physical health.

Dr. Ehrlich received her B.A. at Washington & Lee University, her Ph.D. in Psychology at the University of Maryland, and she completed a postdoctoral fellowship at Northwestern University. Dr. Ehrlich’s research, which lies at the intersection of developmental, clinical, and health psychology, focuses on how social experiences, such as early adversity, close relationships, and socioeconomic status are associated with physical health across the lifespan. In addition to utilizing a variety of methods to evaluate social and emotional functioning, her research incorporates a number of health assessments, including clinical health outcomes, measures of cellular function, and adaptive immunity. Dr. Ehrlich is a recipient of pre- and post-doctoral Ruth L. Kirschstein National Research Service Awards, a NARSAD Young Investigator Grant, an R03 from the National Institute of Child Health and Human Development, and was named a Rising Star by the Association for Psychological Science.

Dr. Ehrlich received $150,542 funding for her NIH R03 (NICHD) proposal entitled Parental Depression and the Early Origins of Disease Across Three Generations.”  When Katie joined UGA in 2016, she began working closely with Dr. Gene Brody (HDFS) and colleagues at the Center for Family Research (CFR) where she got involved in the ongoing longitudinal study of African American families (SHAPE). Youth who joined the study at age 11 are now young adults, and many of them have children of their own.

As part of this grant, Dr. Ehrlich will examine how fluctuations in parents’ (G1) depressive symptoms across a 10-year period are associated with children’s (G2) depressive symptoms and pre-disease risk factors when they reach young adulthood. In addition, they will conduct a pilot study of 60 (G3) children to evaluate links between (G1) and (G2) functioning in relation to (G3) youths’ psychosocial, behavioral, and health measures. This project will set the foundation for recruiting a third generation to the sample, which will then be extended to future projects and will allow them to address questions about the intergenerational transmission of health disparities.

Beginning in January 2019, Dr. Ehrlich will begin work on her Brain & Behavior Research Foundation (NARSAD Young Investigator) grant entitled “Skin Deep Resilience, Proinflammatory Phenotypes, and Depression Risk in Youth” with her postdoc mentors and collaborators Dr. Greg Miller and Dr. Edith Chen with Northwestern University. Also part of the project team is Dr. Gene Brody (HDFS) and Dr. Steve Beach (Psychology). The team has identified an intriguing and initially counterintuitive phenomenon. When studying resilient young adults in longitudinal samples – the participants who, despite adversity, avoided drugs, went to college, and showed few depressive symptoms – were surprisingly not resilient when it came to assessments of their physical health. In fact, these individuals fared worse than their peers, which suggested that the self-control and perseverance it required to “make it” in society was taking a toll on their health.

This research grant is important because studies of “skin deep resilience” have primarily focused on young adults. This project will recruit children (ages 8-14 years old) to examine whether these processes are evident as early as childhood. This developmental question is of particular importance because it will help to establish a time course for when diverging patterns of risk and resilience start to develop. Further, little is known about the underlying physiology that might explain why these resilient individuals develop such poor physical health in adulthood. As part of this study, they will evaluate children’s proinflammatory phenotypes by testing how aggressively their cells respond to bacteria. One hypothesis is that high levels of self-control, while protective for outcomes like academic performance and behavior in the classroom, might be associated with a more aggressive inflammatory response.

Dr. Ehrlich was also recently awarded the NIH Director’s New Innovator Award in the amount of $2,222,879 for her project “Innovative Approaches to the Study of Social Determinants of Health in Children.”

The NIH Director’s New Innovator Award, established in 2007, supports highly innovative research from promising Early Stage Investigators (defined as those within 10 years of completing their terminal research degree or postgraduate clinical training and who have not yet received substantial NIH support). This award is part of the Common Fund’s High-Risk, High-Reward Research program, which was created to accelerate the pace of biomedical discoveries by supporting exceptionally creative scientists with highly innovative research. The program seeks to identify scientists with high-impact ideas that may be risky or at a stage too early to fare well in the traditional peer review process. The program encourages creative, outside-the-box thinkers to pursue exciting and innovative ideas in any area of biomedical research relevant to the NIH mission.

This project began in 2017 when Dr. Ehrlich participated in an UGA Presidential Seed Grant challenge that encourages interdisciplinary research on campus. She submitted an application to study how stressful life experiences might dampen children’s antibody production following influenza vaccination. It was a collaborative project with Dr. Ted Ross, Director of the Center for Vaccines and Immunology at UGA. That project was not funded, but the process of putting together the application solidified Katie’s interest in using vaccinations as a way to evaluate how stress might influence children’s immune systems.

Later that year, Katie applied for the NIH New Innovator Award with the same general focus. The grant mechanism appealed to her for a couple reasons. First, the application was unlike other traditional R01 proposals – instead of a tightly focused and clear plan with preliminary data that is submitted for an R01, the New Innovator Award asks you to think about a scientific challenge that you want to address and how you might take a novel approach to solving that problem. No preliminary data are required, nor do they require the specification of a clear experimental plan (and NIH discourages applicants from submitting specific aims).

The New Innovator Award research is important because the examination of links between social stressors and physical health is difficult to do in childhood, in part because children are generally healthy and show few signs of outward disease. This research will allow them to circumvent some of the challenges they’ve previously faced when trying to examine health markers that have little variability or prognostic utility in childhood.  They will be looking at children’s response to vaccination as an indicator of physical health – a measure that can be considered an in vivo marker of immune function with clinical health relevance.

The odds of success for winning the NIH New Innovator Award are low. It was determined that, out of 600 funded proposals over the last 11 years, only seven other awardees were from psychology departments. So… congratulations Dr. Ehrlich on this huge accomplishment!

Dr. Ehrlich feels that access to unique resources at UGA were a major part of her grant successes. As a participant of OIBR’s Grant Development Program, she workshopped the project idea throughout Year 1 of the program and those discussions plus the focused time to write allowed her to put forward a competitive proposal. The Clinical and Translational Research Unit (CTRU) is a phenomenal facility, with ample space for data collection (e.g., patient rooms) and the staff to help with the visits. In particular, their nursing team is invaluable for blood draws and vaccine administration. Working with vaccines and evaluating antibody production was completely new for Katie, and she was fortunate to rely on the Center for Vaccines and Immunology center (and director Ted Ross, in particular) to assist with study design, sample assays, and answering all of the questions that pop up with this research.

“In addition to being an incredibly kind and supportive mentor, Dr. Gene Brody (HDFS) has encouraged me so much along the way. Also, the collaborative and supportive nature at CFR has far surpassed my expectations for what it would be like to work at UGA, and as a result of CFR’s support, I have been able to move quickly on these applications. I’m confident that these proposals were funded at least in part because of the support and infrastructure that CFR provides for assisting with research,” said Dr. Ehrlich.

So what are the long term goals for this young investigator? Dr. Ehrlich is interested in how these processes play out over time, both within individuals and across generations. She and Dr. Brody are planning to expand on the R03 project to recruit all of the G3 children in the study so that they can more fully examine how experiences in one generation carry forward to the next. She is also interested in new techniques that will provide better insight into the biological mechanisms that might help explain, in part, how social experiences come to influence health.

When asked what she finds most rewarding about her research, Katie replied, “It’s hard to pick just one part! I love how interdisciplinary and collaborative my work is. There’s always something new to learn and a new potential collaboration on the horizon. I’m also really excited about how our work has the potential to inform interventions and public policy – for me, it brings deeper meaning and more urgency to our work.”

Dr. Denise Lewis (HDFS)
Interviewed by Andrea Horsman

OIBR Affiliate Denise Lewis, Associate Professor in Human Development and Family Science, was awarded a $3+ million grant from National Academies of Sciences, Engineering, and Medicine for her project entitled “Community and Family Resilience, Strength and Well-being: Sociocultural Influences on Cambodian and Laotian Refugee Communities’ Responses to Environmental Challenges.” We recently caught up with Denise and asked her to share some information about her project.

How did you first get involved with this project?
I read the request for proposals in October 2016 and began crafting ideas for the project. I knew I’d need a strong team so I traveled to the Alabama coast to meet with leaders in the Cambodian and Laotian communities (where I have more than 20 years of research history). I initially worked with my long-time collaborator, Dr. Desiree Seponski (HDFS) and four community partners. As ideas evolved, I added faculty from the College of Public health: Dr. Sarah DeYoung aids in community psychology research, and there is a disaster preparedness assessment and training component as well.

Tell me about this project and why it is important-
Southeast Asian refugee families living along coastal Alabama have endured cumulative effects of multiple traumas. These include Cambodian refugees’ flight during the Pol Pot genocide that led to approximately two million deaths and an exodus from Laos and Vietnam at the end of the United States-Vietnam War. Families from those nations witnessed deaths of loved ones and continue to experience separations caused by resettlement and adjustment to life as immigrants/refugees. Many families resettled in the United States (US) found that local populations were far from welcoming. Members of the Alabama coastal community faced hostility as they began work in the seafood industry. More recent traumas include the massive destruction caused by Hurricane Katrina and the Deepwater Horizon oil spill. These traumatic experiences can create long-felt social pain and mental anguish, but can also serve as mobilizers for community resilience. It is this foundation of individual, family, and community resilience from multiple traumas that this project will explore.

This project will contribute to three main sociocultural objectives of human dynamics tightly linked to resilience: (1) Engagement of the refugee community through collaboration on, development, testing, and implementation of empirically-informed, community-driven, and community-based programs that produce immediately usable information to prepare for, adapt to, and mitigate effects of environmental challenges; (2) Training community members in research, grant writing, and hazardous risk management skills to facilitate sustainability of developed programs/processes; (3) Creation of models of community-based risk reduction and household production of health including individual, family, and community intersections of sociocultural factors associated with strengths and vulnerabilities.

Tell me about someone who has influenced your decision to work with these communities-
More than 20 years ago, I volunteered to teach English to a Cambodian monk who had just arrived in the United States. One of the community leaders, Mr. Heang Bun Chhun, organized a group of older couples to teach me about Cambodia and Cambodian life- ways as I was teaching the monk. Mr. Chhun’s strength, his willingness to teach and tell his and other refugees’ stories, and his dedication to advancing the good of his community have strongly influenced my decision to continue my work with this and other refugee communities. Through him, I’ve learned that even the most outwardly disadvantaged people possess an inner strength that can be brought to bear on nearly overwhelming circumstances. Refugees, such as those I work with in Alabama, arrived in the US with no material possessions, very limited to no English language skills, and were filled with grief over the loss of many, many family members and their homes, inspire me through their strength and resilience.

What has surprised you most about working on this project?
The most surprising aspect of this project is the willingness of so many members of these two refugee communities to work together, with me and others, to build a stronger community of identity. It is obvious to me that they want to see their cultures survive and thrive. They want to be sure they are providing a foundation for future generations who are proud of their heritage.

What do you find most challenging about this research project?
The greatest challenge is working across three different languages. Although an individual may speak one or more languages, they may not be literate in any of them. Fortunately, I have four main community partners (2 Cambodian and 2 Laotian) who are all fluent in their native language and in English. I also have four translators/transcribers who assist and an additional 20+ members of a cultural advisory board. Without individuals such as these working with me, it would be extremely difficulty to accomplish the goals of this project.

Tell me about some of the people you’ve met-
I’ve known Mr. Heang Bun Chhun for more than 20 years. He escaped from Cambodian in 1976 after losing most of his family. In the early 1980s, he and two other Cambodian refugee men purchased about 180 acres of forestland and created a Cambodian village. He has been my chief Cambodian collaborator since 1996 and is now a close friend. Samoeuy Chim is another Cambodian collaborator. She arrived in the US as a child and has become a very successful businesswoman—she owns several service stations and a chain of doughnut shops. She is constantly “giving back” to members of the local refugee community. Her quiet generosity is inspiring. I’ve known her for more than 20 years as well. I am well known in the Cambodian community—a factor that made creating and now implementing this project a reality.

It has been a pleasure to begin to know members of the Laotian community. The two communities tend to interact so, over the years, I had met many Laotian refugees. However, it wasn’t until Mr. Chhun organized a community meeting in 2016 with leaders from both the Cambodian and Laotian communities that I really began to know Laotian refugees. The primary Lao leader is Mr. Vi- sanou Khamphouy. He arrived from Laos about 40 years ago and is the head of a very large Laotian family. He also engages in mul- tiple community-building activities. These three individuals (Chhun, Chim, & Khamphouy) are collaborators on the grant. There is a fourth individual, Khiaw Srihanouvong, who volunteers his time in the community and in service to the goals of the project. Mr.

Srihanouvong is highly engaged in outreach and in organizing volunteers to serve the communities. He has become a vital part of the project. All of these individuals display strong commitments to their communities and to the project and provide input into how to best meet the needs of their communities.

What is your personal philosophy on what should be done about refugee and immigrant communities?
We should talk to refugee communities about what they see as their greatest need and provide opportunities that respond to those needs. We must recognize the strengths and resilience within these groups. It is vital that we embrace their knowledge, walk with them as partners and, eventually, move out of the way so they can build communities in such a way that they are able to thrive instead of remain in a state of marginality and dependency.

What do you think will change over the next five years?
These communities will thrive by engaging in culturally relevant community building. I already see (and hear) plans for teaching children the languages and traditional dances. Community members are excited about the upcoming community grant writing course (happening in May) and how they’ll work together on issues they have identified in their communities as needing additional funds to address.

What else can you tell me about this research?
This research-practice project has the potential of making generations-long changes to benefit these two Southeast Asian refugee communities.

What benefits (if any) have you experienced by working with OIBR on this grant?
The greatest benefit I’ve received from OIBR on this grant is that I have a team of experienced and knowledgeable people who’ve worked with me from the very beginning to address all the requirements of the funding agencies, to help me think through the needs of the project, and to assist with hiring, budgeting, and managing the grant so that I can focus on the science and implementation of the project.
