About Me

I am a physician-scientist with formal training in both diagnostic radiology and nuclear medicine, specializing in positron emission tomography (PET) and computed tomography (CT) imaging of cancer. I received my MD and PhD degrees in cancer biology from Stanford University and completed my residency and fellowship training at Johns Hopkins Hospital and the University of Southern California.

I joined the MSK faculty in 2009. I am the molecular imaging and therapy representative to the Breast Cancer Disease Management Team, where I work closely with oncologists, surgeons, and pathologists to help provide care to patients with breast cancer. My research focuses on the development and clinical application of PET radiotracers for the detection, staging, and selection of optimal treatments for these patients. For example, I use PET radiotracers that target receptors found on some breast cancer cells to image which patients express these receptors and help determine who may benefit from treatments designed against these receptors. I currently have multiple open clinical trials for patients with breast cancer, supported by grants from the Susan G. Komen for the Cure Foundation and the Department of Defense Breast Cancer Research Program.

My work has been featured in top-rated journals including the Journal of Clinical Oncology, Radiology, the Journal of Nuclear Medicine, and Cancer Research. My work has been reviewed in The Lancet and RSNA News.

Contributing to education is something I highly value. I have mentored more than a dozen residents and fellows; I give local, national, and international lectures; and I am a faculty member for the American College of Radiology PET/CT course.

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. Medicaid and New York State Medicare also provide benefits for care at MSK.
