Faculty
Although the majority of our faculty members and our administrative center are located on the Virginia Harris Cockrell Cancer Research Center at Science Park, our department is uniquely structured with faculty and research support cores present on both the MD Anderson Smithville (Science Park) and Houston (Texas Medical Center) campuses, thus connecting these campuses to facilitate collaboration and growth. Our faculty members are affiliated with the Genetics and Epigenetics Graduate Program of the University of Texas MD Anderson Cancer Center UT Health Graduate School of Biomedical Sciences. Faculty and laboratory membership and participation in the Center for Cancer Epigenetics (CCE), an MD Anderson Center of Excellence that includes members from both Smithville and Houston, further unites these campuses.
