My research spans several areas, but the main focus is the etiology and treatment of mood and anxiety disorders. I am interested in identifying risk factors for depression using electroencephalographic and autonomic psychophysiological measures, especially EEG asymmetry, resting state fMRI connectivity, and cardiac vagal control. Based on these findings, I wish to develop novel and neurally-informed treatments for mood and anxiety disorders, including Transcranial Ultrasound, EEG biofeedback, and Transcranial Direct Current and Transcranial Alternating Current. Other work includes understanding how emotion and emotional disorders influence the way we make decisions and monitor our actions. Additionally, I have published on the assessment of memory and amnesia using event-related potentials, including the assessment of deception ("lie" detection and the polygraph) as well as malingering, and the assessment of the veridicality and the nature of amnesia in dissociative disorders.
