Trained as a behavioral neuroscientist, Jacklynn translates this expertise into her research on emotion dysregulation in clinical populations, notably posttraumatic stress disorder (PTSD). Combined, her research is aimed at deciphering how the brain regulates negative emotional states and how brain regions governing emotion regulation are aberrant in the context of trauma and developing PTSD. As a graduate student, Jacklynn examined aberrant brain functioning in combat-exposed veterans of Iraq and Afghanistan using functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG) methods. She extends this line of work, now involving survivors of acute traumatic injury. Currently, she is investigating how neurocircuitry governing the regulation of fear predicts long-term stress response in this population.
