STEAM Advisor

I am a medical oncologist specializing in the care of patients with soft tissue and bone sarcoma and merkel cell carcinoma. I work very closely with our multidisciplinary team of medical oncologists, surgeons, radiation oncologists, nurses, and patient support advocates to provide the best care and treatment for patients with these diseases. Our highly specialized team recognizes and appreciates the unique challenges that confront our patients, and we are all committed to addressing their needs.

I hope to develop innovative ways to use the immune system to treat these rare cancers. Immunotherapy has proven to be successful in other cancers such as melanoma, kidney cancer and lung cancer. There are many drugs now available that work to enhance the body’s immune system to attack the cancer. In addition, there’s been a great deal of progress using gene therapy to target cancer cells. Specifically this work involves the genetic manipulation of patients' immune cells to recognize and kill their own cancer cells. Exploring these avenues has the potential to make immunotherapy a real option for our patients with sarcoma and merkel cell carcinoma.

As a member of the Immunotherapeutics Clinic (ITC) at MSKCC, we design and conduct early clinical trials using investigational therapies that use the body’s own immune system to fight multiple types of cancer.
