His research primarily involves examining the psychological manifestations associated with executive dysfunction in the mood, anxiety and traumatic disorders. Most recently, his specific recent interest has involved examining the role of “Intolerance of Uncertainty” as a driver of psychopathology and the role of hedonic tone in predicting the presence of comorbid conditions and differential response to treatment. In the past he has used such varied tools as positron emission tomography, the respiratory physiological challenge, and Doppler imaging, in association with a variety of anxiogenic challenges.

He is the chair of a variety of scientific advisory boards, on the editorial board for a number of journals, and has published numerous papers in the areas of Anxiety, Mood, Pain and Attention Disorders.

The focus of his research has been related to Hypoprefrontality, Executive Dysfunction, Intolerance of Uncertainty and Low Hedonic Tone in relation to the development of a variety of comorbidities in association with treatment resistance.
