Speaker Biographies

Dr. David Graham
David Graham is a Consultant Gastroenterologist at University College Hospital, London. He trained at St Bartholomew’s and the Royal London Medical School and completed Gastroenterology training in North East London. He undertook a PhD at UCL focussing on the early detection of esophageal cancer through the utilisation of salivary “liquid biopsies” and artificial intelligence analysis of patient data.
He has a specialist interest in Barrett’s Esophagus, oesophago-gastric cancer, endoscopic imaging technologies and interventional endoscopy. Additionally, he was part of the expert committee devising the BSG guidelines for the management of the pre-malignant and early malignant lesions of the stomach and is part of international research collaborations aiming to improve the early detection of these lesions.
Finally, David has a keen interest in endoscopy training and has helped run many live endoscopy courses at UCH.

Dr. Rehan Haidry
Rehan Haidry is a Consultant Gastroenterologist and Endoscopist at University College Hospital, London, one of the country’s leading teaching hospitals. He has expertise in general gastroenterology and hepatology.
He trained at St Mary’s Hospital, London and completed his gastroenterology training in North East London. He then undertook a prestigious 2-year research fellowship at UCLH, examining novel diagnostic and therapeutic endoscopic techniques in the upper gastrointestinal tract, including endoscopic treatment of early cancers. He has a particular interest in managing and treating patients with acid reflux symptoms and also Barrett’s Esophagus.
Dr. Haidry has ongoing clinical research commitments in the Division of Surgery & Interventional Science at UCL. His research interests are focused on the development of new methods for detecting and treating dysplasia (early cancer) in Barrett’s Esophagus and other pathologies of the gastrointestinal tract. He is involved in coordinating Europe’s largest patient registry, the UK HALO radiofrequency ablation registry which collects nationwide outcomes of this exciting new intervention in patients with early cancer of the esophagus.

Dr. Jason Dunn
Jason Dunn is a Consultant Gastroenterologist at Guy's and St Thomas' Foundation Trust Hospitals. Dr Dunn is also an Associate Professor at King's College London and has a research interest in oesophageal diseases. Dr Dunn is the Chair of Oesophago-Gastric Tumour Group, South East London Cancer Alliance.
His particular interest is early diagnosis of esophageal cancer, using specialist endoscopic techniques to assess Barrett’s esophagus with dysplasia, early esophagus and stomach cancer and colon cancer. He is proficient in Endoscopic Therapy including Endoscopic Mucosal Resection (EMR), Polypectomy and Barrx™ Radiofrequency Ablation (RFA) techniques. He was awarded a CRUK clinical fellowship at UCL and studied use of optical diagnostics and minimally invasive therapies for the treatment of Barrett’s esophagus. He gained his PhD in 2011 and has presented his work at national and international meetings. His work on treatment of Barrett’s esophagus with RFA, and the use of biomarkers to predict cancer progression, has won prizes. At UCL he helped to set up the National UK Barrx™ registry, which recently published 10 year follow up data. He has published in high impact factor journals and book chapters. Current trials as PI include an RCT of Barrx™ RFA for inlet patch and novel non-invasive biomarkers for Barrett’s (SPIT, NEED).
Dr Dunn has trained in POEM and offers this service for patients with achalasia. He is an expert in Eosinophilic Oesophagitis and was an advisor to NICE for treatment of the condition, and senior author on the UK guidelines.

Prof. Marine Camus
Marine Camus (MD, PhD) is a hepato-gastroenterologist specialized in endoscopy. After medical school in Paris, and a master degree in Surgical Sciences, she performed a post-doctoral research fellowship at UCLA (University of California Los Angeles) under the mentorship of Pr Dennis Jensen on the topic of digestive bleeding. She is now a full professor at Sorbonne University in Paris and has joined the Endoscopic Center of St Antoine Hospital in Paris since November 2017. She is strongly involved in digestive endoscopy training for the gastroenterologic fellows in France.
Her clinical research focuses on digestive endoscopy and correlated with the field she has trained in as well as her current clinical practice of interventional endoscopy (hemostasis, EUS, ERCP, ESD). She is the head of the POET Team (Parisian On-call Endoscopic Team), a team performing emergency endoscopies in Paris and surburbs during nights and weekends.
Her research activity focuses on GI bleeding and development of new endoscopic diagnostic and therapeutic tools for biliary tract pathologies after a PhD focused on the study of physical and pharmacological treatments of biliary tract and pancreatic tumors, such as the effect of therapeutic ultrasound cavitation, radiofrequency ablation, or oxidative stress compounds.
