About Dr. Kry
My long-term professional goal is to improve the safety and efficacy of radiotherapy treatment for cancer patients by improving the quality and consistency of such treatments. The proposed project works directly towards this goal by ensuring consistent and quality radiotherapy is delivered to patients enrolled in clinical trials. This will have immediate benefit to those specific patients on clinical trial, and will benefit all patients in the long-term by ensuring that clinical trials generate the optimal results. I am well suited to be a co-investigator on this grant because I have substantial experience in evaluating doses delivered in a radiotherapy setting. This includes clinical experience, working with a wide range of radiotherapy patients undergoing contemporary radiotherapy. It also includes research in patient dosimetry, patient setup, and institution credentialing for clinical trials. Through these experiences I have a solid understanding of radiotherapy as it is currently practiced, the limitations of current practice, and what is necessary to ensure consistent, quality, treatments.
