Specialty/Research Focus
Radiological Physics
Professional Summary:
Research within the physics section of the department of Radiation Medicine at Roswell Park Cancer Institute deals with clinical applications of physics in the treatment of both malignant and benign disease. The Department of Radiation Medicine is undergoing expansion in both its Clinical programs and in its research activities. Currently, we have ongoing projects involving the most recently acquired piece of equipment, known as the gamma knife, used for the treatment of intracranial lesions. We are attempting to characterize the scatter radiation dose distribution within the environs of the gamma knife. Other projects include studies of the properties of electron beams used at extended treatment distances and evaluations of different types of in vivo dosimeters.
Students who perform research under the auspices of the department of Radiation Medicine can expect to gain both theoretical knowledge of medical physics and the practical experience necessary to practice within the field.
