I am a senior lecturer in sport & exercise psychology and a member of the Institute for the Psychology of Elite Performance. My research interests centre on personality in relation to performance and health, with a specific focus on narcissism. In recent years I have received research funding from a variety of sources including the MoD, Rugby Football Union, UK Sport, England and Wales Cricket Board, Sport Wales, and the European Social Fund. Much of my work  is collaborative and involves organisations from the High Performance domain. Current and recent collaborators include the ECB, UK Sport, RFU, MoD, Mountain Training UK, and the Youth Justice Service. I am also a chartered psychologist and associated fellow of the British Psychological Society and a Health Care Professions Council registered sport & exercise psychologist. I have over 15 years’ experience working with high level performers and coaches in sport and military settings on a variety of performance-related issues, and also supervise aspirant psychology practitioners.

I am interested to hear from potential PhD candidates who wish to complete PhDs in relation to personality and performance
