Integrating developmental psychopathology and statistical/molecular genetics, we seek to understand how genetic and environmental factors contribute to the development of alcohol use disorders and related behavioral and emotional health outcomes in diverse populations.

We are interested in:

1) understanding how family processes and sociocultural factors may buffer or exacerbate genetic risk for the development of risky substance use patterns across development, particularly during adolescence and young adulthood,

2) disentangling the genetic and psychosocial pathways underlying the intergenerational transmission of risk and resilience related to substance use disorders and related outcomes, and

3) examining potential differences in pathways of risk and resilience across racial/ethnic groups.

Our goal is to understand how genetic and psychosocial factors predict substance misuse to better inform effective, personalized prevention and intervention for individuals who are at risk.

Research Projects:

The Pathways to College Health Study is a longitudinal study that involves collecting online surveys (questionnaire and daily diary) and DNA data from European American and Latino college students at ASU. The goal for this study is to examine how family and cultural processes (and other relevant environmental factors) in conjunction with genetic factors contribute to alcohol use and related behavioral and emotional outcomes throughout college years. This study was launched in Fall 2020 and data collection is ongoing.

In addition, our lab has access to data from the Collaborative Study on the Genetics of Alcoholism (COGA) and the Spit for Science Study (S4S) through active collaborations with COGA and S4S investigators. 

We also conduct secondary data analysis of the Adolescent Brain Cognitive Development (ABCD) Study, with data access granted by the NIMH Data Archives. 

Dr. Su is accepting new Ph.D. students in the Developmental and Clinical Psychology programs for the 2022-2023 academic year. Please inquire directly with Dr. Su at jinnisu1@asu.edu.

Genes, Environment, and Youth Development

Lab Director and Principal Investigator: Jinni Su, Ph.D., Assistant Professor

Dr. Su is a member of the developmental psychology faculty. Her research focuses on how genetic and environmental influences contribute to the development of substance use and related behavioral and emotional health outcomes. Integrating developmental psychology and statistical/molecular genetics, Dr. Su utilizes a multidisciplinary perspective to understand the interplay between genetic predispositions and psychosocial factors in influencing substance use and related outcomes across diverse populations, with a focus on racial/ethnic minority adolescents and young adults. She applies innovative genetically informed designs to examine the genetic and psychosocial pathways underlying the intergenerational transmission of substance use disorders and related outcomes. Dr. Su also examines potential differences in pathways of risk and resilience across racial/ethnic groups, with the goal to understand mechanisms underlying racial/ethnic disparities in substance use disorders and related health outcomes and inform effective, personalized prevention and intervention efforts. Her research involves self-report data from surveys and interviews and genomic data collected from saliva or blood samples. Dr. Su received her bachelor’s degree in Economics from Beijing Normal University, China. She completed her master’s and doctoral degrees in Human Development and Family Studies at the University of North Carolina at Greensboro. Dr. Su continued as a postdoctoral fellow in the Department of Psychology at Virginia Commonwealth University under the mentorship of Dr. Danielle Dick.

Graduate Students

Angel D. Trevino

Angel is a second-year Ph.D. student in Developmental Psychology. He is interested in studying the pathways through which individual differences, genes, and environmental factors lead to the development of psychopathology in youth. He is particularly interested in how cultural processes interplay with genetic influences on youth outcomes. Outside of the lab, Angel enjoys spending time with his family and dogs. 

Belal Jamil

Belal is a first-year graduate student in the Developmental Psych PhD program. His research interests are in understanding how genetic and environmental factors influence the development of psychopathology (e.g., substance use, internalizing behaviors) in young adulthood, particularly for ethnic minority populations. He hopes to analyze these factors through intergenerational studies and a variety of genetic, behavioral, and cultural measures. In his free time, Belal likes to paint, play video games, and cook.

Lab Coordinator 

Ian McNamara

Ian graduated from ASU in May of 2021 with a B.S. in psychology and intends to pursue a PhD in clinical psychology. In addition to the Gene, Environment, and Youth Development lab, Ian currently works in the Behavioral Alcohol Research for Clinical Advancement lab and is enrolled in the Addiction and Substance Use Related Disorders graduate certificate program. His research thus far has addressed pathways of risk from externalizing behaviors to alcohol use outcomes with a focus on psychosocial factors and athlete populations. Outside of the lab, Ian enjoys reading fantasy, watching sports, and finding new hiking trails.
