My program of research is focused on alleviating the mental health burden of trauma by enhancing our understanding of risk and resilience factors that contribute to the development of traumatic stress, evaluating predictors and mechanisms of successful interventions for traumatic stress, and exploring novel intervention strategies for individuals affected by traumatic stress, including preventive approaches. Risk and resilience to traumatic stress involves a complex interplay of psychological and biological processes; therefore, I aim to integrate neurobiology with behavioral science in my work. Given that trauma is known to contribute to a variety of mental health problems, my work takes a transdiagnostic approach with the goal of identifying core mechanisms of trauma-related pathology that can be targeted in interventions. My work has focused on several high-risk populations including veterans, homeless youth, and urban dwellers exposed to interpersonal violence.
