Gastrointestinal Research Center

David Pascoe, Ph.D., leads the Gastrointestinal Research Center in its exploration of gut function in relation to hydration, nutrition, diseases, development, and recovery. The center studies the structures and mechanisms of gut health and its impact on overall well-being, as well as athletic performance.

The Gastrointestinal Research Center (GIR) focuses on research investigations that provide a better understanding of the functions, dysfunctions, structures, mechanisms, and health of the gastrointestinal tract of animals and humans.

Dysfunctions of the gut greatly impair the functions of hydration, thermoregulation, digestion, nutrition, growth, development, oral drug delivery system, gut microflora, recovery, and sleep. The Gastrointestinal Research Center investigates the gut as a primary factor in health related problems such as obesity, psychological stress-PTSD, autism, and heat stress, as well as diseases such as Celiac, Inflammatory Bowel Syndrome, and Irritable Bowel Syndrome. Auburn University has the scientists and facilities to provide research leadership in gastrointestinal dysfunction investigations.
