Profile

I have studied and worked at the University of Sheffield for around fifteen years, across ScHARR, Psychology and Computer Science. I am currently completing an ICA (integrated clinical academic) doctoral research fellowship. I am a qualified clinical psychologist with a doctorate in clinical psychology. I work clinically with adults with long term conditions, at Derbyshire Community Health Services NHS Foundation Trust. Until commencing the fellowship I held a role as Research Facilitator for the Trust’s Health, Wellbeing and Inclusion division, and I maintain links with the Trust’s Research Team.
