Dr. Zinn received his B.A. degree in 1981 from Plan II at The University of Texas at Austin, where he did research on ribosome structure with biochemist Boyd Hardesty, Ph.D. He received his MD and PhD degrees from the UT Southwestern Medical Scientist Training Program (MSTP) in 1988. His dissertation research under the mentorship of Ronald Butow, Ph.D. concerned yeast mitochondrial genetics. Dr. Zinn then did a residency in internal medicine at Massachusetts General Hospital, followed by a postdoctoral fellowship in human genetics in the lab of David Page, MD, at the Whitehead Institute, MIT. He returned to UT Southwestern in 1993 as an independent research fellow and was appointed to the faculty in 1996. In 2008 he became the director of the MSTP, and in 2013 he was appointed Dean of the Graduate School of Biomedical Sciences. He maintains an active lab in the Eugene McDermott Center for Human Growth and Development. His research program focuses on human genetic growth disorders, including sex chromosome abnormalities, hereditary obesity, and other rare genetic diseases.
