Get to Know Me

I am a pediatric oncologist on the MSK Kids team who cares for children and young adults with solid tumors. I have particular expertise in treating pediatric kidney cancers such as Wilms’ tumor and rhabdoid tumor, pediatric liver cancers such as hepatoblastoma and fibrolamellar carcinoma, and pediatric sarcomas. Through a combination of quality care, education, and research, I strive to improve the outcomes and experiences of children with cancer.

In addition to caring for patients, I conduct research focused on translating basic scientific discoveries from the laboratory into safer and more effective treatments for children and young adults with challenging solid tumors. I investigate how these cancers become resistant to standard treatments, screen new drugs in laboratory models of childhood cancers, and identify markers to predict which patients would benefit from these additional therapies. Ultimately through my research, I hope to move the most promising treatments from the lab and into the clinic to help patients with cancers that have become resistant to standard therapies.

At MSK Kids, I am honored to work with a dedicated team of healthcare professionals. Our doctors, nurse practitioners, nurses, pharmacists, social workers, and others are committed to providing the best possible care for every child and family.
