About Me

I am a board-certified radiation oncologist who specializes in caring for people with genitourinary cancers, including prostate cancer, bladder cancer, and kidney cancers. I also care for patients with gastrointestinal and hepatobiliary cancers. My primary goals are to deliver excellent, compassionate, patient-centered care and to support my patients and their loved ones through their cancer treatment.

I firmly believe that cancer care is not a one-size-fits-all approach. My philosophy is to educate and empower patients with information about their diagnosis so that they can confidently choose a treatment plan that is individualized to their specific needs, personal preferences, and values.

For patients who receive radiation treatment at MSK, we offer several cutting-edge, state-of-the-art technologies. These include image-guided radiation therapy, stereotactic body radiation therapy, proton therapy, and brachytherapy. These techniques allow us to more effectively treat cancer while minimizing side effects. The outstanding clinical care and exceptional technical expertise ensures that radiation treatment is always delivered safely and with precision.

We also place great emphasis on convenience. Our patients can utilize a number of treatment facilities throughout the MSK regional network in New Jersey and New York, including at MSK Monmouth, where I see patients. We are excited to offer several radiation treatment schedules tailored to our patients’ lives. For example, some patients with prostate cancer may be eligible for a radiation treatment regimen that spans days rather than months.

For people interested in participating in clinical trials, we offer several research studies that aim to advance our existing standards of cancer care. I am deeply committed to improving the lives of people with cancer through research and have been involved in both lab research and clinical research for over a decade. As a research fellow in the Bloomberg-Kimmel Institute for Cancer Immunotherapy at Johns Hopkins, I studied how to optimize the combination of stereotactic radiation and immunotherapy and how to use new imaging techniques to monitor the immune response to radiation. I also completed specialized training in immuno-oncology at the National Cancer Institute where I focused on novel radiation-drug combinations and early-phase immunotherapy clinical trials in genitourinary cancers.

As a New York/New Jersey native, it is an honor to be part of Memorial Sloan Kettering and to provide top-notch cancer care to members of this community.

Clinical Trials

As home to one of the world’s top cancer research centers, Memorial Sloan Kettering is typically involved in more than 900 clinical trials at a given time. Currently, clinical trials focused on the conditions I treat are enrolling new patients.

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicare and New York State Medicaid also provide benefits for care at MSK.
