Trauma Anxiety and Stress (TAS) Lab
Our research examines the mechanisms underlying the development and treatment of Posttraumatic Stress Disorder (PTSD) and Anxiety Disorders, predictors of response to exposure therapy for anxiety disorders, and the impact of stress and trauma on brain and emotional functioning. Specific research questions include examining the impact of stress and sex hormones, sleep and cognitive processes on emotional memory consolidation (intrusive memories), fear extinction, and treatment response in individuals with anxiety disorders and PTSD. The aim of this research is to lead to the development of more targeted and effective treatments for PTSD and anxiety disorders.
