Research Summary

Safe and effective use of radiation for the treatment of cancer including external beam and brachytherapy technique development and verification; implementation of new technology in radiation therapy; use of imaging in treatment planning and treatment verification.

Research Interests & Projects

I am interested in research which focuses on the safe and effective use of radiation for the treatment of cancer. Just as technology changes the world we live in, it changes how we treat patients with cancer. With technology advances there are opportunities to develop improved treatments for patients. These new treatments have the potential to improve outcomes, reduce unwanted side effects and reduce the length of treatment time.

One project involved the development of a radiation treatment of the entire scalp producing a uniform radiation dose distribution and limiting the dose to underlying brain tissues. This development made use of the Volumetric Arc Therapy (VMAT) technology developed by Dr. Karl Otto during his PhD studies in Medical Physics undertaken at the BC Cancer Agency and UBC Vancouver campuses. This technology is available clinically through his collaboration with Varian Medical Systems, Inc.
