My research interests focus on the activities of the Imaging and Radiation Oncology Core Houston QA Center (IROC-H). Supported by the NCI and several other grants/contracts, IROC-H is responsible for monitoring radiotherapy facilities participating in inter-institutional cooperative clinical trials funded by the NCI and for providing independent peer review to radiotherapy sites in North America and 55 other countries. In collaboration with Drs. Stephen Kry, Rebecca Howell, Laurence Court and Geoffrey Ibbott (this department), my efforts are directed at improving quality assurance audits and minimizing dosimetry errors encountered at the participating facilities, improving the delivery of radiation doses using advanced technologies, and developing QA audits for photon and proton therapy. My team of 5 IROC-H medical physicists is all focused on the design and development of quality assurance tools and methods to improve the radiation dosimetry for clinical trials as well as determining the root causes of dosimetry errors. IROC-H is entering a new area of focus by applying all of its capabilities and knowledge towards improving radiotherapy dose delivery in other countries outside of North America and Western Europe. A secondary interest of mine involves the calculation and measurement of radiation doses outside of the primary treatment field and then correlating those doses with secondary effects.

Depending on the student's interest, a tutorial in my laboratory would provide experience with radiation dosimetry/measurements, end-to-end QA phantom design, the compilation and analysis of generic trend data for use a QA tools, the measurement of doses outside of the primary treatment field and development of software tools to analyze radiation dosimetry data gathered from use of our anthropomorphic phantoms.
