I have performed over 2900 cholecystectomies thus far. Apart from gallstone surgery, I carry out operations on the liver, the pancreas and the bile duct, by the keyhole and open methods. I also perform general surgery, such as repair of hernias.

I look after my private patients at The London Clinic and the King Edward VII Hospital. I worked as a Consultant Surgeon at the Royal London and St Bartholomew’s Hospitals in London for 22 years (1999 to 2020), where I set up and led the specialist service for liver and pancreas surgery in North-East London. I served as the Serjeant Surgeon to Her Majesty The Queen (2016-23) and prior to that was the Surgeon to the Royal Household (2006-16). I was also Medical Director of The London Clinic for 5 years (2017-22).

I have over 75 publications in surgical journals and have served as a referee (peer reviewer) for 4 international surgical journals. I have raised over £1 million for research into pancreatic and liver disease in the past years. These funds have been utilised in running several research projects at Barts and at the London Clinic. I was an Honorary Reader at the Barts Cancer Institute until 2023. I have been a postgraduate teacher through my consultant years and was an examiner for the FRCS examination in General Surgery from 2015 to 2025.

I grew up in Mumbai, India, and qualified as a doctor from the Grant Medical College. In London, I trained at the Royal Free and University College Hospitals, London, as Registrar, Research Fellow and then Lecturer (Senior Registrar). I was a visiting Fellow at the University of Minnesota with a grant received from the King's Fund.
