My research focuses on developing, evaluating, and implementing practical approaches to behavior change. I combine behavioral science, digital health technologies, and implementation science to address public health challenges such as alcohol and drug use, mental health, interpersonal violence, cancer prevention, and other health-risk behaviors.

My recent work includes adaptive smartphone interventions for adults experiencing homelessness, communication skills training for U.S. Army operational units, strategies to reduce opioid use and overdose, and efforts to improve substance use treatment for people with intellectual and developmental disabilities. I also design and evaluate motivational interviewing interventions and help organizations translate evidence-based practices into routine care.
