Resume/CV

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.

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.

My current research projects focus on prescribed opioid medications, both for management of pain and treatment of opioid use disorder. I am particularly interested in studying the safety of these medications during pregnancy, including consequences for child development, such as risk for adverse birth outcomes and neurodevelopmental disorders. My work utilizes large datasets and epidemiologic methods to help disentangle effects of opioid medications from effects of other factors that may be associated with adverse outcomes, including genetic and environmental factors, and indication for prescription opioid use. 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.

The primary aim of my research is to understand the impacts of prescription and recreational drug use on the development of severe mental illnesses. I am especially interested in understanding how early antipsychotic use may be either protective or harmful against later psychopathology outcomes. In my current projects, I am using large datasets to measure how different types of drug use during youth influence risk for psychiatric hospitalizations. Before joining Indiana University, I received my BS in Neuroscience at UCLA and worked as a post-bac in the National Institute of Mental Health under Dr. Allison Nugent.

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.

I am an IU grad and DPL alum. I’m interested in using approaches from psychiatric epidemiology to examine risk and protective processes that contribute to self-harming behaviors, substance use problems, and related conditions across development. I am particularly interested in research focused on neurodevelopmental conditions, such as ADHD, as well as research that helps to understand and improve health inequities. As an undergraduate, I completed an honors thesis studying racial-ethnic differences in ADHD treatment during adolescence and emerging adulthood. As a post-bacc research assistant in the DPL, I assisted with projects using real-world healthcare data to evaluate the risks and benefits of psychotropic medication use. I am currently pursuing a Ph.D. in Clinical Psychology at the University of Michigan, Ann Arbor.

I am an adolescent researcher with a focus on understanding the emotional development of Black youth, examining how Black youth’s social context (family, friends, school) influence emotion expression and emotion regulation, as well as the role emotion expression and emotion regulation play in Black youth’s decisions to engage in both risk-related and prosocial behaviors. My research seeks to expand our foundational knowledge of adolescent emotional development and situate that knowledge within a sociocultural context for Black youth.

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.

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 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 undergraduate 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).

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.

My primary research interest is the etiology of childhood and adolescent antisocial behavior and the pronounced sex difference in antisocial behavior that persists from childhood into adulthood. I am interested in the genetic and environmental influences on sex differences in the development of antisocial behavior, as well as exploring sex differences in sensitivity and exposure to risk factors, and the role of sex-specific risk factors for antisocial behavior. I am also interested in the possible causal relationships between teenage childbearing and offspring antisocial behaviors. My research uses genetically informative and longitudinal approaches to study the causal associations between various putative risk factors and antisocial behavior.
