NIHR Doctoral Research Fellow
- Specialty Registrar in Trauma and Orthopaedics on the Oxford Deanery
I completed my medical studies at the University of Cambridge. I entered specialty training in Trauma and Orthopaedics in Oxford and completed a DPhil as part of Prof Rees' research group. I was awarded an NIHR Doctoral Fellowship to carry out research with the overall aim of "Improving outcomes for patients having shoulder replacements: guiding patient selection, evaluating cost-effectiveness and informing NHS provision".
My previous research has focused on learning curve modelling and investigating patterns of learning in both elective and emergency Orthopaedic surgery. I have presented my work at national and international meetings and have been awarded several prizes including the SICOT/AAOS Scholarship Prize and the internationally competitive AO Stephan Perren Travelling Research Fellowship.
Alongside my studies, I enjoy tennis and table tennis, and am an active member of the Oxford University Underwater Exploration Group (OUUEG).
