My major research efforts have been in the development and testing of innovative cancer treatment approaches in clinical trials. Primary areas of interest have been soft tissue and bone sarcomas in adults and adolescents, as well as the application of advanced radiation oncology technologies including charged particle radiation with protons and brachytherapy (i.e. placement of radiation sources in close proximity to the tumor to deliver high doses of radiation to the tumor while sparing nearby normal tissue).
