research overview

Nicole Nugent's research interests focus on the interplay of neurobiological and environmental influences on child and adolescent responses to traumatic and chronic stress.

research statement

Dr. Nugent's research has spanned child and adolescent responses to traumatic and chronic stressors including pediatric injury, family violence, sexual abuse, disaster, and HIV diagnosis. She has conducted programmatic research aimed at characterization of neurobiological and psychosocial influences on post-trauma adjustment, toward the goal of developing informed and novel secondary and tertiary interventions aimed at prevention and treatment of posttraumatic stress disorder (PTSD) and related stress-sensitive conditions.
