About me

My research and clinical interests focus on anxiety and related disorders (including obsessive-compulsive disorder [OCD]) and I mentor and train UNC clinical psychology graduate students in these areas. I also teach graduate and undergraduate courses at UNC. Working with many wonderful students and collaborators, I have published over 300 research articles, book chapters, encyclopedia entries, and books on anxiety, OCD, and related topics.

I joined the Clinical Psychology faculty at UNC-Chapel Hill in 2006 and am currently Professor of Psychology and Neuroscience and Director of the Clinical PhD Training Program. My previous positions include Associate Chair of the UNC Psychology and Neuroscience Department (2007-2017), Assistant/Associate Professor at the Mayo Clinic and Mayo School of Medicine (2000-2006), and Instructor at the University of Pennsylvania (1999-2000).

Awards and Recognition

I am fortunate to have received awards for my contributions to the fields of anxiety and OCD, and for mentoring students, from the University of North Carolina, National Institute of Mental Health, American Psychological Association, International OCD Foundation, Mayo Clinic, and my beloved alma mater, Muhlenberg College. I also served as President of the Association for Behavioral and Cognitive Therapies (ABCT) (2014-2015) and as the founding editor of the Journal of Obsessive-Compulsive and Related Disorders (2011-2020).


I live in Chapel Hill, NC with my wife and two daughters (now both away at college). We enjoy days and nights out on the town, attending sporting events, musical performances, and theatre. We also love travelling, visiting the beach and mountains, and exercising/playing various sports. I also play the guitar and piano.
