Jessica L. Barrington-Trimis

Jessica L. Barrington-Trimis is an Associate Professor of Population and Public Health Sciences at the University of Southern California. Her research focuses on adolescent and young adult health, particularly substance use (e.g., vaping, cannabis, tobacco), mental health correlates, and health disparities. She examines longitudinal behavioral patterns, environmental influences (e.g., neighborhood factors, policies), and the intersection of digital media with substance use initiation. Her work emphasizes public health implications for prevention strategies and policy.

Key research interests include vaping epidemiology, flavoring impacts on nicotine use, mental health comorbidities with substance use, and disparities in health outcomes. Recent studies address vaping transitions, cannabis use trajectories, and the role of social networks in adolescent substance use.

Her articles analyze topics such as e-cigarette flavor preferences, dual-use patterns, and vaping-related respiratory symptoms. She has contributed to understanding how psychosocial factors, neighborhood environments, and policy interventions influence youth health behaviors. Notably, her work highlights the importance of addressing flavor restrictions and improving mental health access for vulnerable populations.
