Ashley E. Mason, PhD

Assistant Professor of Psychiatry

Core Faculty, Osher Center for Integrative Medicine

Laboratory Director

Ashley E. Mason joined UCSF's Osher Center for Integrative Medicine in the Fall of 2013. Her research focuses on the biological and psychological experiences of reward-driven eating. To this end, she is conducting several studies focused on the assessment and treatment of compulsive overeating. Specifically, her current studies examine the effects of sugar consumption on subsequent eating behavior and cognitive processes; the roles of the endogenous opioid system in compulsive overeating; the implementation of, and long-term adherence to, a Ketogenic diet for Type 2 Diabetes; and mindful eating interventions targeting reductions in craving-related eating. She completed her Clinical Internship in Behavioral Medicine at the VA Palo Alto Health Care System, her PhD in Clinical Psychology at the University of Arizona, and her undergraduate degrees at Northwestern University.

Rachel M. Radin, PhD

Postdoctoral Scholar

Rachel M. Radin joined the SEA Lab in the spring of 2017. She is a Postdoctoral Research Scholar at the UCSF Department of Psychiatry, Center for Health and Community. Her research interests include clarifying the biopsychosocial processes that contribute to eating behavior and metabolic health in adults. She received an F32 (NRSA) from NCCIH to investigate the impact of a mindfulness intervention (SHINE trial) on stress-related eating and endocrine and autonomic profiles of stress reactivity. Rachel aims to develop integrative health interventions that reduce obesity-related health decline. She completed a PhD in Medical and Clinical Psychology from the Uniformed Services University of the Health Sciences in 2017 after completing a Pre-doctoral Internship in Pediatric Psychology at Mount Washington Pediatric Hospital. She earned an MA in psychology in education from Columbia University and a BA in psychology from the George Washington University.
