Following his fellowships, Dr. Cohen did additional training in endoscopic suturing, submucosal endoscopy, and bariatric endoscopy.

Dr. Cohen's clinical and research interests focus on novel, minimally invasive endoscopic techniques to prevent, diagnose, treat and palliate gastrointestinal conditions ranging from oncology to obesity. These techniques include endoscopic retrograde cholangio-pancreatography (ERCP) for both benign and malignant disease, therapeutic endoscopic ultrasound (EUS), radiofrequency ablation (RFA) for Barrett's esophagus, pancreatic necrosectomy, endoluminal stenting, submucosal endoscopy, endoscopic gallbladder drainage, endoscopic suturing as well as endoscopic resection of complex digestive tract polyps and early cancers through endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD). While on faculty at BIDMC, Dr. Cohen founded the Center for Bariatric Endoscopy to help manage patients with obesity using non-surgical techniques and in 2019 he performed the first Endoscopic Sleeve Gastroplasty at BIDMC. In addition to primary endoscopic weight loss therapies, Dr. Cohen manages patients who have regained weight or had complications following bariatric surgery.

Dr. Cohen has published extensively in many journals, including Cancer ResearchEndoscopy and Surgical Endoscopy and is the author of several book chapters. Dr. Cohen has a strong interest in digital health, entrepreneurship, device development, artificial intelligence as well as nutrition.
