Research Description

Dr. Trim’s research focuses on the development of substance use disorders across the lifespan. Drawing from developmental psychopathology and ecological systems perspectives, Dr. Trim has focused on three major areas of research: 1) Cognitive processes underlying the development of substance use in adolescence and young adulthood 2) Family and environmental characteristics that exacerbate risk for substance use outcomes across development and 3) Exploring antecedents and consequences of substance use changes over time. Consistent with these research areas, he has an overarching interest in longitudinal data analysis and utilizing statistical models of change to capture dynamic patterns of substance use behaviors. He also serves as director of the Substance Abuse/Medical Illness (SAMI) Clinic at the VA San Diego Healthcare System.
