I have studied and worked at the University of Sheffield for over ten years, across ScHARR, Psychology and Computer Science. I am currently a research associate in the Mental Health Research Unit, and I am part of the Centre for Psychological Services Research. I am a qualified clinical psychologist. I work clinically with adults with long term conditions, at the Derbyshire Community Health Services NHS Foundation Trust. I am also the Research Champion for the Trust’s Health, Wellbeing and Inclusion division. I am working on developing my career as a clinical academic.
