TMC Digestive Disease Center Activities and Events


The Enrichment Program provides critical mechanisms to support the overall goals of the Texas Medical Center Digestive Disease Center via the following specific aims:

  • To share and disseminate knowledge gained from the presence of the DDC and in the larger field of digestive diseases
  • To promote and increase interaction and collaboration among investigators and clinicians interested in digestive diseases
  • To foster the scientific and career development of DDC members.

DDC Research Forum


Our DDC research forum is a weekly seminar held during the spring and fall academic months. Seminars are usually delivered by either a national leader in GI research outside the Texas Medical Center or a DDC member. Occasional seminar slots are used to advertise the latest services offered by one of the DDC Cores. The seminar series encourages interactions among basic and clinical investigators across all three consortium institutions. DDC member seminars are free to present research results, clinical studies or works-in-progress as a way to encourage discussion, feedback and overall information exchange. Potential speakers can be nominated by any member of the DDC, who can also act as faculty host (pending approval by the Seminar Committee and the Internal Advisory Committee of the DDC).

During the pandemic, the seminar series has been virtual, though it is pending to return to hybrid in-person/virtual in Spring of 2022.

Questions regarding the DDC Research Forum or suggestions for potential topics and speakers can be directed to Geoffrey Preidis, M.D., Ph.D., head of our Seminar Committee, at or Sara Tristan, DDC Administrator at Join us on Zoom Thursdays at 4 p.m.
