Byron 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 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 nonsteroidal anti-inflammatory drug-induced gastrointestinal injury, with a special interest in the effects of aspirin in the gastrointestinal tract.

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. 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. He has authored over 150 peer-reviewed publications.
