  • Our Mission

    The mission of the Texas Medical Center Digestive Disease Center (TMC DDC) is to facilitate on-going digestive diseases research, promote translational research between basic and clinical areas, develop new projects, nurture new investigators, and provide GI educational activities.

    The TMC DDC supports three basic science cores: Cellular and Molecular Morphology, Functional Genomics and Microbiome, Integrative Biology; and one clinical core: Study Design and Clinical Research.

    Our Pilot/Feasibility and Enrichment Programs support innovative ideas and new investigators in digestive diseases research and foster collaboration which is a key focus of the TMC DDC. The Center draws together a multidisciplinary group of investigators, including basic scientists with proven track records of success, and well-coordinated clinical programs dealing with pediatric and adult GI patients.

    TMC DDC leaders are senior scientists-administrators experienced in directing interactive, multidisciplinary programs. The large, multi-ethnic population of infants and adults with digestive diseases emphasizes the need and the opportunities for the TMC DDC. Various groups involved in GI research and education in the Texas Medical Center work hand in hand with the Center. It is one of only fourteen such NIDDK-funded centers in the United States which promotes coordinated digestive disease activities. The TMC DDC is the only NIH NIDDK-funded digestive diseases center in the southwest United States.
