Board Certifications

Nuclear Medicine

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.


Doctors at Memorial Sloan Kettering work as teams, with specialists from all different areas. This allows us to consider all your needs together, and to give you the best possible care.
