Graduate Research Prize Winners Spring 2014
As an undergraduate at Leeds University, I obtained a first class honours degree in Pharmacology and then graduated in Medicine with honours and distinction in 2003. Following junior doctor training in Oxford and London, I commenced specialty training in Gastroenterology in 2006 in North East Thames. I returned to Oxford in 2009 as a clinical research fellow funded by NHS Blood and Transplant under the supervision of Professors Mike Murphy and Simon Travis and was awarded a DPhil in Clinical Medicine.
During my 4 years as a research fellow I was co-chief investigator of the TRIGGER trial, a pragmatic cluster randomised feasibility trial comparing restrictive versus liberal blood transfusion for gastrointestinal bleeding, published in the Lancet in 2015. The trial was run in partnership with the MRC Clinical Trials Unit and was a collaborative effort with emergency medicine, acute medicine, gastroenterology, critical care and blood transfusion services.
I am also co-investigator for the HALT-IT trial (Tranexamic acid for gastrointestinal bleeding), a trial funded by the NIHR HTA aiming to recruit 8000 patients internationally with acute severe gastrointestinal bleeding. I was involved in the trial design, successful grant application, set-up and championing of the study within UK gastroenterology.
In 2015, I was awarded a National Institute for Health Research Clinical Trials Fellowship which was spent at the Oxford Clinical Trials Unit and Centre for Statistics in Medicine in Oxford, headed by Professors Doug Altman and Sally Lamb. I have formalised training in clinical trials through a combination of “hands on” exposure as well as a diploma in Clinical Trials at the London School of Hygiene and Tropical Medicine and collaborate with clinical trial statisticians on a broad range of methodological projects focusing on design and analytical issues in clinical trials.
My research focuses on the design and conduct of multi-centre clinical trials with a particular interest in cluster randomisation as an efficient method of evaluating treatment strategies. I am involved in the development of range of new indices to be used as endpoints in clinical trials for inflammatory bowel disease as well as several investigator initiated clinical trials.
Between 2010-2015 I have been a direct or co-applicant to over £4.5 million of peer reviewed grant funding.
In 2016, I moved to the University of Western Ontario in Canada as Associate Professor of Medicine and recipient of the John and Susan Macdonald Endowed Chair in Inflammatory Bowel Disease Clinical Research. My clinical inflammatory bowel disease practice is based at University Hospital, London Ontario. I retain a cross appointment at the Nuffield Department of Experimental Medicine, University of Oxford.
