About Me

I am Professor of Psychiatry and Honorary Consultant Psychiatrist at the Department of Psychiatry, University of Southampton, and Southern Health NHS Foundation Trust. I lead a specialist assessment and treatment service for impulsive, compulsive, and behaviourally addictive disorders.

I am affiliated with the Department of Psychiatry, University of Cambridge; and Cambridgeshire & Peterborough NHS Foundation Trust. I collaborate with the National Treatment Service for Obsessive-Compulsive Disorder (OCD) (England and Wales, UK); the National Problem Gambling Clinic (England and Wales, UK); the Department of Psychiatry & Behavioral Neuroscience, University of Chicago (USA); and the BrainPark at Monash University (Australia).

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

(1) developing and validating clinical 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.
