Fan-Chi Su, Ph.D.

Fan-Chi “Frances” Su, Ph.D., is an Associate Professor in the Department of Radiation Oncology at UT Southwestern Medical Center and faculty in the Department’s Division of Medical Physics & Engineering. She earned her bachelor’s degree in radiological sciences from Chang Gung University and her master’s degree in medical physics from National Tsing Hua University, both in Taiwan, before completing her Ph.D. in therapeutic medical physics at the University of Texas Health Science Center at San Antonio. Before joining UT Southwestern, Dr. Su held faculty positions at Yale University and the University of Utah.

Dr. Su has extensive clinical expertise in photon and proton radiation therapy, brachytherapy, and treatment planning system management. At UT Southwestern, she specializes in MR-guided adaptive radiation therapy and plays a key role in advancing personalized ultra-fractionated stereotactic adaptive radiotherapy (PULSAR®) to improve patient outcomes. Her research focuses on functional imaging-based adaptive therapy, artificial intelligence (AI)-assisted radiation therapy, and clinical workflow optimization, bridging innovation with practical applications in radiation oncology.

Dr. Su has written and co-authored numerous publications focusing on advancements in radiation therapy technology, including surface-guided systems and innovations in proton therapy and brachytherapy. Her work also emphasizes quality assurance and dosimetric evaluations to enhance treatment accuracy and safety, as well as adaptive and personalized approaches to optimize outcomes for conditions such as glioblastoma and lung cancer.

She has given numerous national and international invited lectures on topics focused on technological innovations, clinical safety, and optimization of therapy techniques such as quality assurance and error detection in radiation therapy, advances in adaptive and proton therapy, brachytherapy techniques, and dosimetry.
