One area of particular focus is developing partial breast radiotherapy techniques to treat less breast tissue with less radiation to reduce side effects and to shorten treatment times.Another research interest is advancing radiotherapy technologies to treat pancreatic cancer. He is currently writing a textbook review on Gastrointestinal and Hepatobiliary Radiation Therapy and working on a review on minimizing malignancy risks after radiation therapy.He is also actively involved in the development of new drugs and agents to use with radiotherapy to improve cure rates for breast cancer and gastrointestinal cancers. Presently, his group is collaborating with others in developing skin products to decrease skin side effects from breast radiotherapy.
