DPhil Supervision

I have supervised DPhil and MSC graduates for the last 21 years. I currently supervise DPhil projects looking at the use of tests in Paediatric care, the role of AI in supporting the management of multiple long-term conditions (MLTC), methods to support decision-making in integrated care boards, interventions for smoking cessation, and identification of groups at high (health) risk due to extreme temperatures.

My primary research program focuses on managing multiple long-term conditions, the impact of extreme temperatures on health, meta-analysis methods, methodology for studying infectious diseases in children, and assessing complex interventions.

"Unpacking the Black Box"

Rafael Perera

DPhil MSc MA

Director Medical Statistics and Director of Graduate Studies

  • Professor of Medical Statistics
  • Fellow at St Hugh's College

I am the Director of Graduate Studies in the Nuffield Department of Primary Care Health Sciences (NDPCHS), tasked with providing academic leadership, oversight, administration and advocacy for the department’s graduate students.

I am also the Director of the Statistics group  (NDPCHS), and as part of this role,  I am involved in multiple research activities within the department. However, my primary research interest is Monitoring for managing long-term conditions (e.g. Type 2 diabetes, hypertension, etc) individually or jointly (sometimes called multimorbidity).

I lead a large group of methodologists working across multiple clinical areas and have been PI of large Programmes of work and Theme lead for NIHR-funded infrastructure programmes (NIHR BRC, NIHR ARC, and NIHR MIC). I set up the NDPCHS fully accredited Clinical Trials Unit as its original Statistical Director.

I sit on various national and international panels and boards influencing healthcare policy at different levels (funding boards, steering groups, data monitoring boards, etc.) and have held multiple editorial positions. I am a Statistical Editor for the BMJ (since 2011) and BMJ Medicine (since 2022). 

I am also the Director of Research Methodologies at the Centre for Evidence-Based Medicine (CEBM) and a fellow at St Hugh’s College Oxford.
