I am the Director of Radiobiology in the Department of Radiation Oncology at WSU. I currently teach the Radiobiology course in the Graduate Program. I also teach at a number of international courses on radiation oncology, and host a week-long NIH sponsored course at WSU that focuses on the integration of radiobiology and radiation physics into clinical practice.

Research Interests

While my background is pure radiobiology, the overlap between models of radiation damage and the physics required to understand those models has generated a number of interesting research projects for me within the medical physics arena.

My current Research Interests include, but are not limited to:

  • Molecular basis for clinical radiation resistance and diversity seen in the response to radiation therapy, including the study of cancer stem cells.
  • Development of a complete system of treatment planning based on biologically effective dose to improve our ability to account for variability in biological factors such as radiosensitivity, hypoxia and cell proliferation from patient to patient.
  • Investigation of soy isoflavones to enhance radiotherapy.
  • Gene therapy and therapeutic use of stem cells for radioprotection of normal tissues.
  • Development of high-LET radiotherapy.
  • Nanoparticles to enhance the radiation effect on radioresistant tumors.


I do advise Master's student in their thesis work in the medical physics program. The research is usually biologically focused, including some lab work, with a heavy lean towards clinical applications of the outcomes and possible inclusion into the planning of hypofractionated treatment schedules.
