About Me

I am a board-certified nuclear medicine doctor with expertise in PET/CT, nuclear cardiology, general nuclear medicine, and radioimmunotherapy. I have been practicing nuclear medicine for more 15 years and have been at MSK since 2002.

Working at MSK is especially rewarding because I can focus on my area of interest, thyroid cancer. As a member of the Thyroid and Lymphoma Disease Management Teams, I work with other doctors to provide the best cancer care.

I serve as an investigator on many thyroid cancer clinical trials. My research focuses on thyroid cancer imaging and therapy. I am particularly interested in using PET imaging with the iodine labeled compound I124.

I am also very involved in medical education and teaching and supervising the molecular imaging and therapy trainees in the Department of Radiology.

Clinical Trials

Research is integral to our mission at Memorial Sloan Kettering, and clinical trials help us discover better forms of patient care and treatment. For you, this could mean access to a new therapy or therapy combination. Click to see a list of the trials I’m currently leading.


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.
