  • About

    Dr. Peter Grau is an Assistant Professor in the University of Michigan’s Department of Psychiatry, staff psychologist at the Ann Arbor VA, and research investigator at the VA Center for Clinical Management Research. Dr. Grau’s research focuses on advancing the implementation of evidence-based approaches for post-traumatic stress disorder (PTSD) across multiple levels of care and healthcare settings, with the goal of improving mental health outcomes, especially for Veterans and those with common comorbidities. His work also explores the intersection of human- and digitally-delivered interventions across multiple timescales and other therapeutic avenues of change to design and implement scalable interventions delivering effective treatments for patients. Dr. Grau’s research aims to shift healthcare practice toward data-driven, culturally informed treatment for trauma exposure and PTSD nationally and globally.
