Zhenyu Xiong, PhD

Division of Radiation Physics

Dr. Xiong received his Ph.D. from The State University of New York at Buffalo in 2018 under the supervision of Daniel R. Bednarek, Ph.D. He then completed his clinical training at UT Southwestern Medical Center’s Medical Physics Residency Program. During his time at UT Southwestern Medical Center, Dr. Xiong also completed the training programs in Stereotactic Body Radiation Therapy, Gamma Knife, and VMAT-TBI. Dr. Xiong specializes in brachytherapy planning and delivery, external beam treatment planning and delivery, machine and patient-specific QA, TBI/TSE, CyberKnife, and Gamma Knife. Dr. Xiong’s research interests include image guidance in radiotherapy, surface guided radiation therapy, novel treatment techniques, the use of Monte Carlo simulation in radiotherapy, and fabrication of patient-specific 3D printed devices for external beam treatment and brachytherapy. Dr. Xiong enjoys fishing, cooking, board games, and traveling with his family.
