I have been a consultant general and colorectal surgeon since 2017 and I am an expert on surgical treatment of inflammatory bowel disease and rectal cancer. I have been trained in advanced minimally invasive surgery during my Higher Surgical Training in London and the South West Thames region which I completed in 2015. Subsequently, I had further specialist training in complex anal fistula and inflammatory bowel surgery at St. Mark’s Hospital, St. George's and St. Thomas Hospital in London, where I gained extensive experience in minimally invasive surgery for low rectal cancer, pouch surgery, complex fistula repair and deep endometriosis.

During my training, I embarked on a scientific collaboration with the Hepatobiliary Department of the University of Verona, Italy which led to a PhD awarded in 2012. Publications from the thesis include association of familial adenomatous polyposis (FAP) and primary duodenal cancer.

I have performed over 4000 general and colorectal surgical procedures including laparoscopic right hemicolectomy, laparoscopic anterior resection, complex anal fistulae repair, and abdominal wall hernias. I am also a national trainer on colonoscopy accredited by the JAG Endoscopy Training System.

As a colorectal surgeon, I was part of the Royal Derby Endometriosis Centre team which achieved the status of accredited unit from the British Society for Gynaecological Endoscopy in 2021. I am also a member of the European Endometriosis League.

I am the Surgical IBD lead at Royal County Sussex Hospital where I work in close contact with the IBD dietician team and gastroenterology colleagues in order to optimise Crohn’s patients prior to their surgery.

I am an Honorary Senior Lecture at the Brighton and Sussex Medical School. Currently, I am enrolled on an online course to achieve a Diploma in Football Medicine supported by FIFA medical network.
