Research Interests

Trained as a behavioral neuroscientist, Dr. Fitzgerald’s research translates what we know about how the brain generates and regulates emotions to better understand the emergence of emotion dysregulation in clinical populations, notably anxiety, depression, and posttraumatic stress disorder (PTSD). Using functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG) recording, Dr. Fitzgerald’s research uncovers variations in the neurobiology as well as time course of emotion dysregulation in these disorders. Using mixed methods, her work integrates what is known about aberrant neurobiological functioning with peripheral markers of emotional responding.
