My research specializes in the use of functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG) methods to study the neurocircuitry underlying symptom provocation and emotion regulation in internalizing disorders, particularly posttraumatic stress disorder (PTSD). Currently I investigate the impact of acute trauma on amygdalo-frontal functioning responsible for fear acquisition and extinction. In addition, I examine how aberrations in this neural network after trauma interact with and predict disruptions in adaptive stress responding.
