In memoriam: Gary Humfleet, PhD


Gary Humfleet, PhD

Gary Humfleet, PhD, passed away peacefully on April 11, 2024, surrounded by family and friends, after a long battle with cancer. Dr. Humfleet was a longtime member of the faculty of the UCSF Department of Psychiatry and Behavioral Sciences, where he conducted research, provided mentorship to postdoctoral fellows, and was also active in patient care. He was nationally known for his work in smoking cessation clinical trials, particularly related to health disparities, treatment of chronic smokers, and those with co-occurring disorders.

Dr. Humfleet held leadership roles in 13 NIH-funded clinical trials and had been a faculty mentor in NIH-funded postdoctoral training programs (T32s and R25s) for the past 30 years at UCSF, including the Substance Use Disorders Treatment and Services Research Training Program and the Learning for Early Careers in Addiction and Diversity (LEAD) Program, both funded by the National Institute on Drug Abuse (NIDA). He led the weekly NIDA T32 substance use research seminar, in which his effective teaching and mentorship has had a lasting impact. Although he provided close mentorship to several individual fellows, every fellow in the NIDA T32 program should be considered as part of Dr. Humfleet’s legacy, as his work in the program enriched all of their training,

For over 20 years, Dr. Humfleet also served as clinical director for the Habit Abatement Clinic where he oversaw the functioning of a clinical enterprise which treated thousands of Bay Area patients and studied the implementation of innovative therapies for the treatment of tobacco dependence that are widely used today. He was a much valued collaborator, working productively with many UCSF and Stanford faculty colleagues, including Sharon Hall, PhD; Ricardo F. Muñoz, PhD; Janice Tsoh, PhD; Joseph Guydish, PhD; Kevin Delucchi, PhD; Jodi Prochaska, PhD, MPH; Meredith Meacham, PhD, MPH; and Danielle Ramo, PhD, among others.

Among his scientific leadership roles, Dr. Humfleet was a member of the Center for Scientific Review Study Section, “Behavioral and Social Consequences of HIV/AIDS,” and a member of the Steering Committee of the National Action Plan Addressing LGBT Tobacco Use.

Dr. Humfleet received his BA in psychology from Bowling Green State University and his PhD in clinical psychology from DePaul University. He completed a postdoctoral fellowship at Northwestern University Feinberg School of Medicine and became a member of the faculty. He was also a faculty member at California State University, Long Beach before joining the UCSF Department of Psychiatry and Behavioral Sciences in 1993.
