MD, MSc, PhD, FRCS Eng (Gen Surg)


Specialises in

I am one of Brighton’s leading surgeons. Practicing at the University Hospitals of Sussex NHS Trust and the Montefiore Hospital. I specialise in minimally invasive keyhole surgery techniques including laparoscopic surgery for gallbladder disease, inguinal hernia, acid reflux, weight loss and gastrointestinal conditions. I also assist with diagnosis and treatment using upper GI endoscopy.

I began my career in general surgery in 2006. During my training, I have completed three fellowships in bariatric and esophago-gastric surgery under the tutorage of leading surgeons. I have achieved extensive experience in upper gastrointestinal and bariatric surgery and offers all types of minimally invasive treatments.

While I was training, I have gained my PhD in liver regeneration which has been published widely. My research interests have included minimally invasive surgical techniques, improvement of patient care through innovation and the metabolic implications of obesity. I have been widely published in numerous field-related, peer-reviewed journals.

I will provide you with an experienced and honest account of the options, risks and benefits of advanced laparoscopic surgery, putting your safety and well-being as the first priority.
