With his thesis "Evaluation of Roux-en-Y gastric bypass as a primary and secondary bariatric surgery and its effect on type 2 diabetes", he obtained a PhD qualification in 2017, and diabetes and metabolic surgery have remained his main areas of interest and research ever since.

Anastomosis leak rate and operative mortality are both 0 (zero) during the 800 bariatric surgeries completed so far, and the results of all surgeries are uploaded to the National Bariatric Surgery Registry, which is publicly available at nbsr.e-dendrite.com.

Over the years, he has received detailed training in oesophageal and reflux surgery, and has years of experience performing both.
