Research Interest

  • Improve cancer patient treatment outcome through the design of i-SAbR clinical trials
  • Innate and adaptive immune responses generated by tumor irradiation with stereotactic ablative radiotherapy (SAbR)
  • Investigate strategies to combine immunotherapy with SAbR (i-SAbR) for cancer treatment
