Research interests

As a Clinical Psychologist working with young people with obsessive-compulsive disorder (OCD) and related conditions, I became interested in understanding the mechanisms underlying these disorders with the goal of improving treatment outcomes. My current research is primarily focussed on understanding risk factors and clinical characteristics associated with OCD and body dysmorphic disorder (BDD) in youth. I am interested in using genetically-informative approaches to address these questions, in order to tease apart genetic and environmental influences on OCD and BDD. I am using data from several longitudinal twin studies, including the Genesis 12-19 study (G1219) and the Twins Early Development Study (TEDS).

My other research interests include developing effective treatments for young people with OCD and BDD, and establishing effective strategies for their dissemination. I have been involved in a number of clinical trials, both as a trial therapist and a Principal Investigator.

Alongside my research, I have the privilege of continuing to work as an Honorary Principal Clinical Psychologist at the National and Specialist OCD, BDD and Related Disorders Clinic for Young People at the Maudsley Hospital. I also teach on several courses at King’s College London, including the Doctorate in Clinical Psychology, and I deliver training on OCD and BDD to mental health professionals nationally.
