Nicola Anne-Knowles


Stefan completed his undergraduate training at Leicester, followed by postgraduate surgical training in Oxford and London. During this time he undertook a PhD at Imperial College in oesophageal cancer metabolism, and he now leads a group creating metabolism-based tools to improve outcomes for patients with upper gastrointestinal (UGI) cancer.

Clinically, his key interest is minimally invasive surgery for UGI cancer. He also treats all general and benign upper gastrointestinal surgery issues, including gallbladder surgery, hernia surgery, anti-reflux and hiatus hernia surgery, and surgery for achalasia.
