Dillon Li, M.D., Assistant Professor, is a radiation oncologist at UT Southwestern Medical Center focused on treating breast cancer.

After graduating from Peking University Health Science Center summa cum laude, Dr. Li received his M.P.H. from the University of Cincinnati College of Medicine and his medical degree from the University of Kentucky College of Medicine. He completed his radiation oncology residency at Memorial Sloan Kettering Cancer Center, which provides one of the most robust training programs in the world for lymphoma and pediatric radiation oncology. During his residency, his research focused on the genomic basis of radiosensitivity and advanced radiotherapy delivery technologies, and he has a keen interest and passion in furthering our precision and personalized radiation oncology program. In fact, as a radiation oncology resident, he was awarded an ASCO Young Investigator Award to this end.
