Research Clinical Psychologist
I am a research clinical psychologist within O-CAP. The overall aim of my research is to improve psychological treatments for people experiencing severe mental health problems, with a particular focus on developing the psychological understanding and treatment of harmful grandiose delusions. I have worked as a trial therapist on several of the O-CAP trials including the Feeling Safe Study - a clinical trial investigating a novel psychological intervention for persecutory beliefs, and the OWLS trial - a pilot randomised controlled trial of a sleep intervention designed specifically for psychiatric inpatients.
In addition to my role within O-CAP I also work as a consultant clinical psychologist for the Oxford Cognitive Therapy Centre, which provides specialist CBT training and supervision. My area of specialism is CBT for psychosis and I am the course lead for the OCTC/University of Oxford PGCert in Enhanced CBT: Psychosis and Bipolar. I am an HCPC registered Clinical Psychologist and BABCP accredited CBT practitioner.
