Dr. Junhan Cho is an Assistant Professor of Research in the Department of Preventive Medicine in the Keck School of Medicine at the University of Southern California. He is the Director of Methodology and Statistics for the USC-Health, Emotion, & Addiction Laboratory (USC-HEAL), which conducts interdisciplinary research on mental health problems and health-related behaviors. With a strong interest to develop advanced research methodologies, Dr. Cho's research aims to address how diverse social contexts and psychological vulnerabilities intersect to increase risk of addictive behaviors. Based on his research background on Human Development and Family Science throughout master and doctoral programs, his studies incorporate both theoretical and methodological frameworks necessary to conducting longitudinal and prevention studies on youth health risk behaviors with a focus on the psychosocial processes influenced by family and community contexts. His current studies include: 1) developmental patterns of conjoint multiple health risk behaviors; 2) longitudinal risk and protective pathways linking early contextual stressors to mental health problems in adolescence; and 3) interaction of social contexts and biological factors influencing psychological vulnerability to addictive behaviors including substance use across adolescence and young adulthood.
