Genes, Environment, and Youth Development (Su)

Keywords: gene-environment interplay, substance use, family relationships, adolescence, young adulthood, ethnic/racial minority, health disparities

Lab Research Area:

Integrating developmental psychology and statistical/molecular genetics, we seek to understand how genetic and environmental factors contribute to the development of alcohol use disorders and related 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.

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

Jinni SuDr. 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.

Undergraduate Research Assistants:

Claudia Grochalska (see picture attached)

I am currently a junior double majoring in psychology and neuroscience and minoring in Slavic studies. My research interests include substance abuse and addiction, as well as treatments and preventative measures. I am planning on pursuing a career in research and am very excited to gain hands-on experience working in Dr. Su’s lab. Feel free to contact me at cgrochal@asu.edu

Mahasin Shigdy

Shigdy is a 4th-year undergraduate student of psychology. She is interested in researching deviancy in racial, sexual and gender minorities within the field of developmental psychology, specifically how the broader and local social, cultural and political landscape may influence the behaviors of adolescents from minority groups.
