My research focuses on mental and cognitive health, including causes and consequences of autism, posttraumatic stress disorder (PTSD), depression, and cognitive decline. I also study the psychological, behavioral, and physical health outcomes of trauma and stress, including PTSD, depression, intimate partner violence, and health-risk behaviors. I am particularly interested in the effects of trauma on health across generations.

In addition to studying the effects of psychological trauma, I conduct research on the effects of playing professional football, including physical injury, as part of the Football Players Health Study at Harvard Medical School.
