Staff Profile

Introduction

I work as a Consultant Clinical Psychologist in the Psychosis pathway in Gateshead and Newcastle, and am Trustwide Lead for Psychological Interventions in Psychosis for CNTW Trust.  I have an Honorary role with the Population Health Sciences Institute at Newcastle University. I am involved in a number of research trials investigating the treatment of people with distressing psychotic symptoms.  

Research Interests

My research interests stem from and inform my work as a  psychological therapist. I am a clinician in an Early Intervention in Psychosis service in the NHS. In this role I work with people who have suffered distressing psychotic symptoms such as hallucinations or delusional beliefs. The task I have as a clinician is to work collaboratively with a person to make sense of how and why they experienced the problems they had, how they can manage any persisting difficulties, and what will help keep them well in the future. Consequently, as a researcher I am interested in improving our understanding of the processes that lead a person to experience distressing psychotic symptoms like voices, or visual hallucinations. This research shapes and refines the models we draw on to help understand the development and maintenance of the distressing symptoms. This process of drawing on an empirically supported model and marrying it to the unique experience of the person is called formulation. This formulation aids the process of selecting the optimal interventions that helps alleviates a person’s distress and helps them remain well. Hence, I have two main areas of research interest which cover a) psychological processes in hallucinations and delusions, and b) formulation in cognitive behavioural therapy.

Postgraduate Supervision

I currently supervise a number of doctorate of clinical psychology research projects as well as a part time PhD. I have supervised successfully to completion a Ph.D,  2 M.Phils, a Doctorate of Counselling Psychology award, and around 60  Doctorate of Clinical Psychology degrees.
