For more information on the doctor and patient care, please visit the clinical profile. Biography Dr. Luis Sifuentes-Dominguez is studying basic mechanisms of inflammatory bowel disease. He is supported by a departmental, NIH-sponsored Child Health Research Career Development Award and is working closely with Dr. Ezra Burstein in UT Southwestern’s Department of Internal Medicine’s Division of Gastroenterology to understand the molecular basis of early-onset IBD. Using cutting-edge genomic and proteomic approaches, together they have identified novel genes that play a role in early-onset IBD.
