Lewis graduated from Dartmouth College in 1978 and earned his medical degree from Albert Einstein College of Medicine in 1982. He completed his residency in Internal Medicine at Montefiore Medical Center in 1985 and his fellowship in Gastroenterology at Mount Sinai Medical Center in 1987. Lewis was appointed Clinical Professor of Medicine in 2002 at Mount Sinai School of Medicine, where he continues to teach today.
He co-chairs the International Conference of Capsule Endoscopy[3] and coordinated the Consensus Conference statements to guide capsule usage. He is past president of the New York Society for Gastrointestinal Endoscopy and New York Academy of Gastroenterology and has served on the board of the American College of Gastroenterology. Lewis has written scientific papers and has authored 3 books; all in the field of gastrointestinal endoscopy. He co-authored the technical document behind the American Gastroenterological Association's position statement concerning occult and obscure gastrointestinal bleeding and the ICCE consensus statement[4] for clinical application of capsule endoscopy. He also helped develop a scoring index for inflammatory bowel disease seen on capsule endoscopy.[5]
Lewis has published widely on gastroenterological research and co-authored multiple books including: Gastroenterology for the House Officer (1989), Flexible Sigmoidoscopy (1996), Gastrointestinal Endoscopy Clinics of North America; Enteroscopy (1999), and Capsule Endoscopy Simplified (2010). He also holds editorial positions at multiple medical journals including: Gastroenterology, Digestive Diseases and Sciences, American Journal of Gastroenterology, Gastrointestinal Endoscopy, Southern Medical Journal, Endoscopy, Journal of Clinical Gastroenterology, and The Medical Letter.[citation needed]
