About Me


MD, Boston University School of Medicine


Radiation Oncology - Memorial Sloan Kettering Cancer Center

I am a board-certified radiation oncologist who has expertise in using advanced techniques to treat cancer. These include image-guided radiation therapy, intensity-modulated radiation therapy, stereotactic radiosurgery, and proton beam radiotherapy. I am also actively involved in cancer clinical trials. I work to take ideas developed in the lab and translate them into actual trials and treatments that can benefit people with cancer. I am a member of the NRG Oncology colorectal and non-colorectal gastrointestinal cancer committees and the National Cancer Institute’s Rectal-Anal Task Force. My work has been published in Nature, Science, Lancet Oncology, Clinical Cancer Research, International Journal of Radiation Oncology and Biophysics, and Cancer.

At Memorial Sloan Kettering, we approach treating cancer as a team. I work closely with surgical and medical oncologists, radiologists, and pathologists. I can confidently tell my patients that they will receive the best care in the world because of the team of experts that will support them every step of the way. I make sure all my patients are aware of who is on their care team, our individual roles, and how we work together to create a personalized treatment plan.

I also make sure my patients have a solid understanding of their diagnosis. I take time to explain how radiation therapy fits into treating their disease, as well as all the potential benefits and side effects. While many patients have concerns about radiation therapy, I hope that after meeting with me, they and their families feel reassured about what lies ahead. 

Clinical trials, in my opinion, offer patients an opportunity to get the most progressive cancer care available. I know that the decision to participate or not participate in a trial can make people anxious. Ultimately the decision is a very personal one for patients and their families. I hope that by explaining the ins and outs of clinical trials, I can help guide my patients to make the right decision for them.

After patients leave my office, I hope that they feel that they have a strong advocate who will stop at nothing to ensure they are getting the best treatment. 

I can confidently tell my patients that they will receive the best care in the world because of the team of experts that will support them every step of the way.
