Having completed the top junior house officer post at Guy’s and St. Thomas’, he undertook core medical training at Charing Cross and West Middlesex Hospitals followed by specialist training in gastroenterology and general medicine within the North West London region between 2003 and 2010. Four years were spent at the specialist St. Mark’s Hospital, including three years of post-graduate research within the Wolfson Unit for Endoscopy for which he received a Doctorate of Medicine degree from Imperial College London in 2010. Two years of training were spent at Imperial, including a 6 month ERCP fellowship at Hammersmith Hospital.  His published work is mainly within the fields of interventional endoscopy and capsule endoscopy, and he continues to peer review articles for international journals.
