Dr Pavlidis is a clinician-scientist specialising in Gastroenterology and Endoscopy.

His clinical expertise lies in providing a holistic and personalised approach for patients with acute and chronic gastrointestinal symptoms that may result from the interaction of the gut-brain- microbiome axis (like irritable bowel syndrome), immune mediated inflammatory conditions (ulcerative colitis, Crohn’s disease) or following chemotherapy/immunotherapy/stem cell transplantation for cancer (graft versus host disease, checkpoint inhibitor colitis).

He is a JAG accredited endoscopist for upper and lower GI diagnostic and therapeutic procedures. As a core member of the IBD team at King’s he provides surveillance colonoscopy for patients at high risk of colorectal cancer, including those with a long diagnosis of ulcerative colitis and people with combined liver and gut inflammation like PSC-IBD.

Polychronis holds an appointment with King’s College London as a Clinical Lecturer in the School of Immunology and Microbial Sciences. His ambitious translational research programme funded by major national funding streams (NIHR, MRC), charities (CCUK, Guts UK) and other stakeholders aims to deliver stratified medicine approaches in chronic gut inflammation as well as inform evidence-based practice nationally and internationally. He has presented his research work at regional, national and international fora receiving multiple awards and published in high impact journals like Nature Communications, Cell Reports and Gut. Polychronis has contributed to leading national and international guidelines as well as consensus statements on personalised medicine approaches in IBD and checkpoint inhibitor induced colitis.

As a Fellow of the Higher Education Academy he is a keen endoscopy trainer, supervisor and mentor for doctors in training and research students undertaking projects in translational medicine.

Currently he is the Risk and Governance Lead for Gastroenterology at King’s College Hospital.
