I received my bachelor's degree at the University of Wisconsin Madison under the direction of mentors Loren and Jean Chapman, and completed my graduate training at the University of Minnesota under the direction of mentor William G.. Iacono. Following an internship at the VA medical center in Minneapolis, I joined the faculty of the Department of Psychology at The  University of Arizona in 1992, where I am currently Distinguished Professor of Psychology, Cognitive Science, and Neuroscience.

My research involves using electroencephalographic and autonomic psychophysiological measures as endophenotypes in the quest to identify risk factors for depression. I am interested broadly in the etiology and treatment of mood and anxiety disorders.  Specific approaches include the investigation of whether asymmetrical frontal brain activity may serve as a marker of risk for depression, the examination of whether alteration of cardiac vagal control may predict  treatment response in depression, and the investigation of how neural systems underlying cognitive control may be altered in anxiety disorders.

Additionally, I have published on the assessment of memory and amnesia using event-related potentials, including the assessment of deception and malingering, and the assessment of the veridicality and the nature of amnesia in dissociative disorders. 

I enjoy teaching, and I hope it shows.  I teach courses ranging from enormous introductory-level survey courses to small graduate-level courses, and I mentor graduate and undergraduate students who work in the psychophysiology laboratory.  Each semester, at least a dozen undergraduate research assistants are involved in research in the laboratory.  Please contact me if you are interested in the possibility of joining the laboratory.
