DPhil Supervision
My current research interests include methods for meta-analysis, and methods for observational studies in behavioural medicine and hypertension in particular. My publications, listed on my webpage at the department of primary care health sciences, give the best overview of my research.
I currently supervise part-time DPhil students on the Evidence Based Health Care (EBHC) programme and a full-time DPhil student in the primary care department, as well as several MSc students.

I am the course director of the MSc in Evidence Based Health Care Medical Statistics, a continuing professional development course for those in full-time clinical practice seeking expertise in medical statistics.
As a medical statistician, most of my research, whether I'm leading the project or supporting colleagues, is intended for clinical journals. My chief methodological interests are in meta-analysis.
I am a member of the Diabetes UK research grants panel, and an Associate Editor of the journal BMC Diagnostic and Prognostic Research.
Graduate students: I am currently supervising two students on DPhil Evidence Based Health care and one student on DPhil Primary Care, and several MSc students. At present I do not have capacity for additional DPhil students: if you are a potential doctoral student seeking a supervisor, please visit the list of supervisors advertising projects in the department.
