About Me

I am Professor of Psychiatry at the Department of Psychiatry, University of Southampton, and Honorary Consultant Psychiatrist at Southern Health NHS Foundation Trust. I lead a specialist tertiary assessment and treatment service for impulsive, compulsive, and behaviourally addictive disorders. I also founded and Direct the NHS (UK) Southern Gambling Treatment Service.

My primary collaborations are with: the Department of Psychiatry & Behavioral Neuroscience, University of Chicago (USA); BrainPark at Monash University (Australia); the National Treatment Service for Obsessive-Compulsive Disorder (OCD) (Herfordshire, England and Wales, UK); and the National NHS Problem Gambling Clinic (London, UK).

My research and clinical work focuses on impulsive, compulsive, and behaviourally addictive problems. This involves three main areas:

(1) developing and validating clinical & research tools
(2) measuring cognitive problems and brain circuits that contribute (including vulnerability markers)
(3) improving existing treatments and developing new ones.

I have particular interests in conditions such as adult attention deficit hyperactivity disorder (ADHD), gambling disorder, trichotillomania (hair pulling disorder), skin picking disorder, and obsessive-compulsive disorder. I also study how impulsive and compulsive problems exist along a continuum (or dimension) in the general population.
