My primary interests are child and adult responses to traumatic stressors (e.g., physical and sexual assault, motor vehicle accidents, losing relatives to homicide and combat/war-related trauma).   I am specifically interested in how acute stress disorder (ASD) and post-traumatic stress disorder (PTSD) develop following trauma, and in the treatment of these disorders. In particular I research processes that influence the development and maintenance of posttraumatic stress and ways of improving our current treatment methods for posttraumatic stress disorders.
