Dennis Savaiano, Ph.D.
Professor of Foods & Nutrition and Former Dean
at Purdue University

Dr. Savaiano has researched lactose intolerance for the past 20 years, where he has attempted to identify the dietary factors that can improve lactose tolerance. Formerly, he served as the associate dean and assistant director of the Agricultural Experiment Station Human Ecology at the University of Minnesota. Dr. Savaiano is a native Californian with degrees from Claremont McKenna College (BA in Biology) and the University of California at Davis (MS and PhD in Nutrition). He was a Professor in the Department of Food Science and Nutrition at the University of Minnesota from 1980 through 1995, and moved to Purdue University in 1995.

William J. Sanborn, M.D.
Chief, Division of Gastroenterology and Director at University of California San Diego

Dr. Sandborn serves as the Chief, Division of Gastroenterology and Director at University of California San Diego Inflammatory Bowel Disease Center and Professor of Clinical Medicine. Dr. Sandborn directs a large clinical research unit devoted to the conduct of clinical trials in inflammatory bowel disease, where he supervises a multi-investigator team of physicians, research fellows, nurses, and study coordinators. With his physician collaborators, he evaluates and develops new diagnostic modalities and medical therapies for inflammatory bowel disease. He is internationally recognized for his contributions in the fields of biotechnology therapy, clinical pharmacology, conduct of clinical trials, diagnostic and treatment of pouchitis, epidemiology and natural history, and endoscopic and radiographic imaging techniques. He has published more than 408 articles including articles in the New England Journal of Medicine, the Lancet, JAMA, the Annals of Internal Medicine, and Gastroenterology. His research includes clinical development and clinical pharmacology related to inflammatory bowel disease. From April 1993 to December 2010, Dr. Sandborn was head of the Division of Gastroenterology and Hepatology, Mayo Clinic, Rochester, MN and from January 2011 to present, the Division of Gastroenterology, University of California San Diego, La Jolla. Dr. Sandborn is extremely well regarded and well known within the investment community and is considered one of the key leading gastroenterologists in the United States for pharmaceutical research and clinical trial work.

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.

Todd Klaenhammer, Ph.D.
Director of the Southeast Dairy Foods Research Center and Distinguished Professor - Food Microbiology, Genetics, Genomics at North Carolina State University

Todd R. Klaenhammer obtained degrees in Microbiology (B.S), and Food Science (M.S. & Ph.D) from the University of Minnesota. In 1978, he joined the North Carolina State University and currently holds faculty appointments in the Departments of Food, Bioprocessing and Nutrition Sciences; and in the Departments of Microbiology and Genetics. His group has published over 270 articles on dairy lactic acid bacteria, their bacteriophages, and probiotic cultures and their genomic traits. Todd is Fellow in the American Association for the Advancement of Science, the American Academy of Microbiology, the Institute of Food Technologists, and the American Dairy Science Association. In 2001, he was elected into the National Academy of Sciences. In 2009, the Board of Governors of the 17 Campus University of North Carolina System, awarded his group the prestigious O. Max Gardner award for excellence in research across the entire system. In 2010, the International Dairy Federation awarded his group the 2010 Eli Metchnikoff Award in Biotechnology and in 2015, the Japan Bifidus Foundation awarded Todd the Tissier Medal for work on probiotic lactic acid bacteria.

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.
