Assistant Professor, Behavioral and Brain Sciences Program Dr. Richards will be reviewing applications for new graduate students for Fall 2026 admission. I am a health psychologist whose research focuses on why people engage in health-promoting behaviors, particularly behaviors that reduce the potential harms of alcohol, cannabis, and other drug use. I have an early career development award from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) to study the motivational processes of recovery from alcohol use disorder during and after participation in Dry January and Sober October. Recent interests include "natural" health behavior change (e.g., New Year's resolutions), multiple health behavior change, and alcohol-related risk for chronic disease (e.g., cancer).
