Previously, Dr. Prinz spent 21 years at the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health, where he served as Chief of the Lipid Trafficking and Organelle Biogenesis Section in the Laboratory of Cell and Molecular Biology.
Organelle biogenesis is the process by which new structures within a living cell are made and how membrane contact sites and lipids affect the ability of a cell to maintain stable internal conditions upon changes in its extracellular environment. Defects in lipid metabolism and organelle biogenesis are associated with numerous diseases. By gaining insight into the basic processes in cells, Dr. Prinz is committed to furthering the understanding of how defects in these areas contribute to human disease.
Among his notable scientific accomplishments, he discovered the structure and function of oxysterol-binding protein related-proteins (ORPs), a large, conserved family of lipid-binding proteins that play a role in keeping lipid balance and reside at membrane contact sites. Dr. Prinz found that ORPs bind cholesterol and other sterols in a water-repelling pocket and can transport sterols between membranes both in vitro and in cells. He also discovered where they reside and one of the ways ORPs operate.
Dr. Prinz earned his undergraduate degree in biochemistry at Vassar College, then pursued graduate studies in philosophy at Columbia University. He earned his doctorate in microbiology and molecular genetics at Harvard University, where he also completed postdoctoral studies in cell biology.

Robert Timmerman, M.D.
Professor and Chair, Radiation Oncology
Holder of the:
- Effie Marie Cain Distinguished Chair in Cancer Therapy Research
Robert Timmerman, M.D., whose research helped lead to the development of a method of delivering radiation that has transformed cancer treatment, became chair of the Department of Radiation Oncology in March 2022.
An expert in diseases of the central nervous system, including cancer of the brain, spine, and lung, Dr. Timmerman has championed the use of precise, noninvasive, radiosurgical tools that employ multiple angles to deliver radiation. This approach reduces the levels of toxicity, allowing patients to tolerate the treatment better with fewer side effects. Working with other researchers, he developed a method – known as stereotactic ablative radiotherapy (SAbR) or stereotactic body radiation therapy (SBRT) – that uses sophisticated image guidance and tracking to safely deliver radiation. This seminal contribution is widely regarded to have transformed the field of radiation oncology.
Dr. Timmerman joined UT Southwestern in 2004 as Professor and Vice Chair for Clinical Affairs in the Department of Radiation Oncology and Director of the Annette Simmons Stereotactic Treatment Center. He has been Clinical Director of Radiation Oncology since 2014.
He graduated from Iowa State University with a bachelor’s degree in nuclear engineering and from University of Tennessee with a master’s degree in reactor physics. After finishing medical school at University of South Dakota, he completed a residency in radiation oncology at The Johns Hopkins Hospital.
He is a Fellow of both the American Society for Radiation Oncology and the American College of Radiology. In 2019, Dr. Timmerman received UT Southwestern’s Patricia and William L. Watson Jr., M.D. Award for Excellence in Clinical Medicine.
