Current Personnel
Director
Michael Zvolensky, Ph.D.

Dr. Zvolensky is a Distinguished Professor in the Department of Psychology at University of Houston and Director of the Research on Emotion, Substance Use Treatment Outcomes, and Racial Equity (RESTORE) Laboratory and Substance Use Treatment Clinic. He has published over 800 peer-reviewed articles and books/book chapters on the co-occurrence of anxiety and stress-related psychopathology with substance use disorders, health behavior problems, and physical illness (e.g., chronic pain). His work is globally aimed at eliminating inequalities in psychopathology, addictive, and other health risk behaviors through translational research. He has utilized a variety of methodological tactics in his research program, including community-based participatory research (CBPR), laboratory studies, epidemiologic-field (cross-national and prospective), Ecological Momentary Assessment (EMA), and randomized clinical trials. He has been involved in over 70 NIH grants as PI, Co-PI, or co-investigator. His research program has received awards from numerous organizations, including the American Psychological Association, Anxiety and Depression Association of America, College on Problems of Drug Dependence, Association for Advancement of Cognitive and Behavior Therapy, and Association of Academic Health Centers.
A major contribution of Dr. Zvolensky’s laboratory has been to elucidate why people who experience anxiety/depressive-related vulnerabilities are more prone to substance use disorders; and why people with substance use disorders are more prone to anxiety/depressive-related disturbances. His team has led efforts to develop integrative theoretical models of anxiety-substance use disorder comorbidity that identify (malleable) cognitive-affective mechanisms underlying their association. This work is important for designing targeted assessment batteries that can be used to identify high-risk individuals most in need of (specialized) intervention; elucidating mechanisms underlying anxiety/depressive-substance use disorder comorbidity; and developing 'next generation' treatments for these conditions that target the most etiologically potent facets. Within this context, Dr. Zvolensky’s work collectively falls in three, interrelated streams that deal with (a) transdiagnostic processes underlying emotional disorder-substance use disorder comorbidity; (b) mediating and moderating factors involved in the expression, onset, and maintenance of anxiety/depression psychopathology for groups subject to health inequalities; and (c) theoretically-driven and process-based treatment development work that is community-friendly.

Co-Directors
Lorra Garey, Ph.D.

Dr. Lorra Garey is a Research Assistant 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 among underserved and vulnerable populations 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.

In particular, Dr. Heggeness aims to elucidate clinically relevant correlates, consequences, and explanatory mechanisms of affect-driven substance use behaviors to help address mental and physical health disparities often observed among underserved populations.
