Biography

I am a professor and director of radiosurgery in the Department of Radiation Medicine. As a medical physicist in radiation therapy, my role is to ensure the safe, effective and accurate delivery of radiation to our patients as well as the protection of the general public from our treatment activities. I am the lead physicist for our stereotactic radiosurgery (SRS) program. Through these efforts, I spend most of my time clinically working with patients requiring treatment for primary or metastatic intracranial disease, ensuring the most accurate treatments possible. SRS treatments include the smallest and highest dose-per-fraction treatments delivered anywhere in radiation therapy, so my focus is on highly conformal delivery and planning techniques.

My research interests include methods to improve the accuracy of treatment alignment and delivery strategies, with the goal of reducing the total spatial uncertainty in SRS treatments, and to develop new treatment planning strategies that result in very robust yet efficient treatment plans for SRS patients. I also work with graduate students and faculty in medical physics on research efforts to more precisely measure doses from modern treatment systems.
