Brian M. D'Onofrio, Ph.D.

Professor

My research seeks to understand the etiology, assessment, and treatment of child and adolescent psychopathology using multiple designs, including quasi-experimental designs, longitudinal research, and intervention studies. My recent research has focused on using and combining several advanced epidemiologic approaches to better understand the consequences of perinatal risk factors, particularly medications during pregnancy, and the risks and benefits of psychiatric and pain medication for the individuals themselves. Furthermore, my research is focused on better understanding health disparities, particularly among vulnerable and marginalized groups of individuals. Most of my research consists of secondary data analysis of large datasets (e.g., national Swedish datasets, datasets of 30,000 twin pairs in Sweden, and health insurance claims datasets in the United States). I also conduct intervention and health services research, which is currently focused on how to best assess behavioral health problems in community settings, including primary care clinics, behavioral health clinics, emergency departments, educational institutions, and criminal justice settings.

Patrick D. Quinn, Ph.D.

Assistant Professor, Department of Applied Health Science

Adjunct Assistant Professor, Department of Psychological and Brain Sciences

I study the causes and consequences of substance use. My research ranges across substances (e.g., from cigarette smoking to opioids) and across the lifespan (e.g., from prenatal drug exposure to medication treatment for ADHD in adults).

Much of my current research examines pain and its management with opioid medications, using longitudinal data on individuals and families and methods from epidemiology and behavioral genetics. I am also interested in understanding the risks and benefits of other medications that have the potential for abuse (e.g., ADHD medications).

From 2014 to 2018, I was a postdoctoral researcher in the Developmental Psychopathology Lab, and I am still an active collaborator with the lab. I received my doctorate in clinical psychology from The University of Texas at Austin and completed my APA-accredited pre-doctoral internship at the Indiana University School of Medicine.

Note. I am available to serve as a primary advisor for doctoral students in the Clinical Science Program.

Lauren M. O'Reilly

I am interested in studying the etiology of suicidal behavior in adolescence through adulthood. To do so, I analyze longitudinal, population-based registers from Sweden and use genetically-informed designs to examine the extent to which genetic and environmental factors are associated with suicidal behaviors. These large databases and designs allow for the examination of causal relations between previously explored risk factors and later suicidal behavior. I am currently working on three main areas of research: 1) the intergenerational transmission of suicidal behavior using a Children of Siblings and Twins design, 2) the association between a variety.of psychosocial risk factors (e.g., aggression and bullying) and suicidal behavior in an adolescent twin sample, and 3) short-term risk factors for suicidal behavior post-contact with outpatient specialists. I am also interested in how macro-level policy changes interact with suicidal behavior, including the Affordable Care Act young adult mandate and parity legislation.

Emma N. Cleary

I am broadly interested in studying how early-life influences impact later functioning. I am particularly interested in conducting research on pregnancy-related risks, including substance use in pregnancy. In my current project, I am evaluating the association between the use of medication-assisted treatment for opioid use disorder during pregnancy and adverse birth outcomes (e.g., small for gestational age, preterm birth) in children using a population-based sample in Sweden. Before joining the Developmental Psychopathology Lab in 2020, I received my BA in Psychology and Modern Foreign Language from Syracuse University and worked as a project coordinator at Penn State.

Marianne Chirica

My research broadly focuses on examining the etiology, risk, and resilience factors that contribute to anxiety and depressive symptoms and related outcomes (i.e., suicidal behavior) over time. My research aims to identify and analyze potential risk or protective factors, particularly among at-risk patients, that are vital to better understand, predict, and prevent suicidal behavior. Using a developmental approach to psychopathology, my research assesses various units of analysis across the lifespan, such as behavioral (i.e., suicidal behavior), sociocultural (i.e., racial and ethnic differences) and biological (i.e., medications used) markers that interact both cross-sectionally and temporally to predict developmental trajectories of anxiety and depressive symptoms. This work will ultimately help identify those at heightened risk for suicide and suggest potential targets for interventions. Before joining the Developmental Psychopathology Lab in 2021, I received my MS degree in Psychology: Clinical Counseling from Rosalind Franklin University of Medicine and Science and am a licensed professional counselor.

Alynna Summit

I received my B.A. in Psychology in 2019 and my M.A. in Psychological Science in 2021 at the University of North Carolina Wilmington. Currently, I am a Health Behavior doctoral student at Indiana University's School of Public Health. My research interests encompass aspects of substance use. Specifically, I am interested in prescription drug use and misuse. Previously, I studied prescription stimulant misuse among college students, with a primary focus on how college students perceive other college students who misuse prescription stimulants. Now, my work has shifted focus to prescription opioid use among individuals experiencing chronic pain. With this research, I am interested in predictors of adverse outcomes related to prescription opioid use for chronic pain management, as well as the development of statistical models to measure these outcomes. I am also interested in aspects of mental health and the stigmatization of substance use.

Research and Data Scientists

Martin E. Rickert, Ph.D.

I have an extensive background in scientific research with specific expertise and interests in data modeling, statistical estimation and technical computing. Recently, my efforts have focused on using genetically-informed, quasi-experimental designs to explore the scope and specificity of risk factors for adverse birth outcomes, neurodevelopmental disorders, severe adult psychopathology, cognitive/intellectual functioning, and long-term, social outcomes. A key component of my work in the lab and in collaboration with database experts in Sweden involves solving "big" data issues. This includes [1] developing algorithms and writing the software needed to extract and integrate information from the population registers and [2] implementing scripts that enable us to fit complex models (e.g., cross-classified random effects, survival models with time-varying covariates, etc) on Karolinska's computational servers that support data-intensive, high-performance computing tasks.

Kelsey Wiggs

I am broadly interested in the etiology and treatment of neurodevelopmental problems (e.g. symptoms of attention-deficit hyperactivity disorder, seizures, and autism spectrum disorders) across multiple levels of analysis and time scales. In the Developmental Psychopathology lab at IU, I work with Dr. Brian D’Onofrio on two main areas of research using quasi-experimental designs and large longitudinal data sets. The first examines the extent to which perinatal risk factors impact neurodevelopmental problems. The second assesses the safety of medications independent of stable genetic and environmental factors within an individual. Current projects examine 1) the association between prenatal exposure to antiepileptic drugs and offspring birth defects, ADHD, and ASD, 2) the association between ADHD medication use and psychosis, and 3) the association between antidepressant use and seizures.

Ayesha C. Sujan, Ph.D.

Ayesha Sujan, PhD, is a postdoctoral research fellow in the Kaiser Permanente Division of Research specializing in maternal mental health and substance use. She completed her doctoral training in the Department of Psychological and Brian Sciences at Indiana University – Bloomington and her clinical internship at the Medical University of South Carolina. Though her doctoral training focused on clinical psychology, her training spanned multiple disciplines, including developmental psychology, epidemiology, and pharmacology. She also received her master's degree in Human Development from Cornell University and did her ungraduated studies at Tulane University where she double majored in psychology and studio art.

Broadly speaking, she conducts translational research focused on preventing early exposure to risk factors from having adverse consequences on child development. Her research initially focused on early-life adversities, particularly abuse and neglect, and then expanded to include the prenatal period. Though she studies the consequences of a number of pregnancy-related risk factors, including early and advancing maternal age at childbearing and short and long interpregnancy interval, her work mainly focuses on in-utero exposure to psychoactive substances (e.g., antidepressants, opioids, and cannabis) and risk for adverse birth outcomes (e.g., preterm birth) and neurodevelopmental problems (e.g., autism spectrum disorder and attention-deficit/hyperactivity disorder).

Alice C. Schermerhorn, Ph.D.

My research interests are in the area of developmental psychopathology and focus on associations between exposure to stressors like interparental conflict and children’s socio-emotional development and adjustment. I investigate temperament to identify which children are at greatest risk in the context of stress. My research also seeks to identify mechanisms underlying the stress-adjustment problems relationship, such as neural processes and cortisol reactivity. In addition, my research examines transactional associations between stress and child behavior, including whether children exacerbate (or even alleviate) stress in their environments.

Erikka B. Vaughan, Ph.D.

I am broadly interested in the etiology of depression in children and adolescents. While research has highlighted an array of risk factors for depression, I am interested in learning more about the specific mechanisms by which these risk factors result in depression in some adolescents and not in others. As there is empirical evidence for an association between pubertal timing and outcomes of depression in adolescence, I am currently working on a project examining predictors of variations in age of menarche in girls. In examining these factors, I am utilizing a longitudinal design with a large, nationally representative sample.
