Lorra Garey, Ph.D.

Dr. Lorra Garey is a Research Associate Professor at the University of Houston. She earned her Ph.D. in Clinical Psychology from the University of Houston. Her primary research interests focus on elucidating and attenuating health disparities by examining the interplay between substance use and psychological vulnerabilities and addressing malleable risk factors, including tobacco use, in the context of transdiagnostic interventions. Within this model, Lorra is particularly interested in the efficacy of brief, personalized feedback interventions to reduce tobacco use, alcohol use, and symptoms related to anxiety and depression among smokers with co-occurring psychopathology and tobacco dependence.
