Zach Mannes is a fourth year graduate and National Institutes of Health (NIH), National Institute on Drug Abuse predoctoral fellow in the department of Clinical and Health Psychology.

Research Interests

Zach is a member of the Intervention Research Advancing Care Equity (i-RACE) 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. As a NIDA predoctoral fellow he is pursuing research in the area of opioid and marijuana use among retired professional football players.
