About me

I joined the Clinical Psychology faculty at UNC-Chapel Hill in 2006. I am currently Professor of Psychology and Neuroscience, as well as Director of the UNC Anxiety Clinic. My previous positions include Associate Chair of the UNC Psychology and Neuroscience Department, Associate Professor at the Mayo Clinic and Mayo School of Medicine, and Instructor at the University of Pennsylvania.

My research interests focus on anxiety disorders (mainly obsessive-compulsive disorder [OCD]). I teach graduate and undergraduate courses at UNC and also train clinical psychology graduate students in how to implement state-of-the-art assessment and treatment techniques for anxiety/OCD. Working with many wonderful students and collaborators, I have published over 250 research articles, book chapters, and encyclopedia entries, along with 12 books on anxiety, OCD, and related topics. I am also Editor-in-Chief of the Journal of Obsessive-Compulsive and Related Disorders.

I live in Chapel Hill, NC with my wife and two daughters. We enjoy days and nights out on the town, attending our daughters’ dance, sports, and musical recitals, travelling, visiting the beach and mountains, watching Carolina sports teams, and exercising/playing various sports. I also play the guitar and piano.
