He teaches residents and medical students at Baylor College of Medicine and the affiliated Michael E. DeBakey VA Medical Center. His research support has included the NIMH, NIAAA, and the American Heart Institute. Clinical research focuses on treatment of affective disorders, especially prediction of treatment response and development of more objective measures of disease severity, its underlying behavioral mechanisms, and its change during treatment. Preclinical human research concerns the neurobiology of behavior, such as impulsivity and motivation, which may be basic to bipolar disorder and its most severe complications, including suicidal behavior. Basic research focuses on pharmacological and developmental aspects of behavioral sensitization to stimulants and other potential models for recurrence in affective disorders. His work has resulted in over 280 refereed publications, plus reviews and book chapters.
