Dr. Barrington-Trimis is an epidemiologist and Assistant Professor of Population and Public Health Sciences at the University of Southern California. She directs the USC Epidemiology of Substance Use Research Group and is a faculty member in the USC Institute for Addiction Science and the USC Norris Comprehensive Cancer Center. Dr. Barrington-Trimis' research focuses on investigation of the rapidly changing tobacco and alternative tobacco landscape. Her work aims to identify intra-individual psychological, behavioral, and social processes associated with nicotine use in adolescence and early adulthood, and to elucidate the behavioral consequences (e.g., transition to more harmful patterns of substance use) and physiological consequences (e.g., adverse respiratory health effects of e-cigarette use) of varying patterns of nicotine product use in adolescence, with the goal of informing regulatory efforts to protect adolescents and young adults.
