Presentations & Publications

Research Interests:

My main areas of research interest are in bariatric surgery: (i) basic science in particular the changes in gut peptides post surgery, (ii) from a clinical perspective in investigating outcomes and complications of bariatric surgery and (iii) novel techniques for weight loss including bariatric endoscopy and embolisation. I engaged in a PhD degree at Imperial College London investigating these further.

My Bachelor of Science research concentrated on the role of heat stress and ischaemic preconditioning in myocardial protection
