About Me

I am a board-certified radiation oncologist who develops and prescribes radiation therapy treatment plans for patients diagnosed with cancer. I serve on many disease teams at Penn State Cancer Institute, including brain and central nervous system, gastrointestinal, genitourinary, gynecological and thoracic disease. Together, we work to advance the prevention, diagnosis and treatment of cancer.

I have been involved in significant research on the use of radiosurgery for brain tumors and combining immunotherapy with radiotherapy to treat aggressive bladder cancer. I was the co-primary investigator and radiation oncology lead for a Big Ten Cancer Research Consortium multi-institutional clinical trial on using immunotherapy and radiotherapy to treat bladder cancer.

I am proud to use my specialized training and experience to help people face a cancer diagnosis with hope and strength.
