Research Interests:

The social determinants of mental health; mental health services and policy research; implementation science; clinical decision-making; mental health workforce development; health equity; mixed methods; and community-based participatory research.

Current Research:  

My academic mission is to improve population-level mental health and to increase the availability of quality mental health services to all who need them. Trained as an implementation scientist and clinical psychologist, my mental health services and policy research is inherently interdisciplinary and uses both qualitative and quantitative methods.

My research straddles three overlapping domains of inquiry:

  1. Examining the social, political, and economic determinants of mental health and mental health service provision
  2. Investigating implementation efforts to improve mental health service access and quality
  3. Understanding and improving the structural and organizational factors that influence clinicians' decision-making.
