Jong Oh Kim, PhD, DABR

  • Clinical Assistant Professor, Radiation Oncology
  • Medical Physicist, UPMC Hillman Cancer Center

I provide clinical physics services in the areas of Gamma Knife radiosurgery at UPMC Presbyterian as a full-time physicist and external beam radiation therapy and brachytherapy at UPMC Passavant as a part-time physicist for the routine physics works and Monthly QAs for a treatment machine, a CT, and treatment planning system. My research has focused on patient motion study during the Gamma Knife. In addition, I continue my interest in verification using Monte Carlo simulation of radiation therapy and portal imaging technique.

Teaching Activities:

  • Teaching Gamma Knife Machine Calibration and QA in Gamma Knife Course
  • Teaching Gamma Physics Residents about Gamma Knife Physics and Machine QA
