Brett Goshe, PhD

Primary Mentor: Elyse Park, PhD, MPH

Dr. Brett Goshe is a postdoctoral clinical research fellow at Massachusetts General Hospital/Harvard Medical School. He received his Ph.D. from the University of Connecticut, specializing in health psychology and behavioral medicine. Dr. Goshe’s research and clinical practice focuses broadly on the mental health and treatment intervention development for vulnerable and underserved populations, particularly lesbian, gay, bisexual, and transgender (LGBT) individuals. The LGBT community, in contrast to the general population, experiences disproportionate rates of psychosocial problems, including poverty, substance abuse, cancer diagnosis, and most mental health conditions. These syndemic (i.e., overlapping epidemics) concerns present as increased potential for health-risk behaviors, such as sexual risk-taking, smoking, and substance abuse. Dr. Goshe seeks to develop a research program that evaluates these intersecting biopsychosocial processes and provides a scientific basis for addressing them clinically (e.g., adapting empirically-supported interventions).
