Zachary Mannes, M.S., M.P.H.

BiographyZach Mannes

Zach Mannes is a graduate student and former National Institutes of Health (NIH), National Institute on Drug Abuse (NIDA) predoctoral fellow in the departments of Clinical and Health Psychology and Epidemiology. Zach graduated from Virginia Tech in May 2014 with Bachelor of Science degrees in Psychology and Human Development. His academic interests lie in clinical health/medical psychology, with a research focus on examining correlates of substance use among underrepresented populations. Over the next several years he hopes to further his training in the translational biopsychosocial sciences related to substance use. In the future he would like to work in an academic center, with a strong focus on developing behavioral interventions to reduce substance misuse and improve health outcomes in underserved and at-risk populations. In his free time Zach enjoys napping, traveling, hanging out with friends, and watching the Lord of the Rings trilogy on a continuous loop.

Research Interests

Zach is a member of the Intervention Research Advancing Care Equity (iRACE) lab under the mentorship of Dr. Nicole Ennis. He has previously studied correlates of substance use among people living with HIV, specifically the association between affective states, heavy drinking, and illicit drug use. Zach will examine the unique effects of different aspects of pain (i.e., intensity, catastrophizing, interference, or acceptance) on opioid use, depressive symptoms, and HRQOL among National Football League retirees.
