W. Allan Walker, M.D.
Director of the Division of Nutrition at Harvard Medical School
Dr. Walker has a longstanding interest and commitment to nutrition research, particularly on the role of nutritional factors in maintaining the integrity of the intestinal mucosal barrier to host defense during the perinatal period. He was the first recipient of the Conrad Taff Professorship in Nutrition at Harvard Medical School in 1990. The research efforts of his laboratory have contributed substantially to a better understanding of the role of breast milk and its inherent growth factors on the development of the gastrointestinal tract and the role of short and long term malnutrition on the integrity of the mucosal barrier to host defense against bacterial colonization and against the uptake of macromolecules (antigens and toxins) which may result in neonatal and childhood intestinal disease states (necrotizing enterocolitis and gastrointestinal allergy). Dr. Walker served for six years on the Committee of Nutrition of the American Academy of Pediatrics (1977-1983) and received the Nutrition Research Award (Borden Award) of the American Academy of Pediatrics in 1984 and the Hugh Butt Award for Excellence in Clinical Nutrition Research from the American Gastroenterologic Association in 1998. He has also served on Nutrition study sections at the NICHD and NIDDK institutes and the Advisory Council of NIDDK at NIH and recently served as a member of the task force to establish a five-year nutrition research plan at NICHD. Dr. Walker is the author of 12 textbooks and over 500 research and review articles.
Byron L. Cryer, M.D.
Professor of Internal Medicine - Digestive and Liver Diseases and an Associate Dean at Southwestern Medical School, University of Texas Southwestern
Byron L. Cryer, MD, obtained his BA degree from Harvard College, Cambridge, MA, in 1982, and his medical degree from Baylor College of Medicine, Houston, TX, in 1986, where he also completed his internal medicine residency training from 1986 to 1989. Dr. Cryer obtained his gastroenterology fellowship training at The University of Texas Southwestern Medical Center at Dallas (1989-92), where he has remained as a member of the gastroenterology faculty.
Dr. Cryer's clinical interests are in general gastroenterology. His specific areas of interest are acid-peptic diseases of the upper gastrointestinal tract. Specific disease states of interest are Helicobacter pylori-induced ulcer disease and nonsteroidal anti-inflammatory drug-induced ulcers.
Dr. Cryer’s primary research interest has been in the pathogenesis of peptic ulcer disease. His research focus has been clinically oriented in that he has exclusively studied the pathophysiology of these processes in humans. Recent investigations have explored the mechanism of gastrointestinal toxicity of nonsteroidal anti-inflammatory drugs (NSAIDs) within the stomach and duodenum. The most recent aspect of NSAID investigation has been an evaluation of the cyclooxygenase (COX)-2 specific NSAIDs.
Within the AGA, Dr. Cryer has held many leadership positions. He is the past chair of the AGA Underrepresented Minorities Committee and a prior member of the AGA International Committee, AGA Institute Research Policy Committee, and AGA Institute Education and Training Committee. He has also led several AGA-sponsored public awareness campaigns to reduce the GI risks of NSAIDs and other commonly taken pain medications. Dr. Cryer currently holds the position of councillor-at-large on the AGA Institute Governing board..
