Get to Know Me

I am a pediatric hematologist-oncologist on the MSK Kids team with special training in treating children and adolescents for cancer. I also help survivors stay healthy after their treatment is over.

I am doing research related to survivorship to see how we can best take care of people who have been treated for childhood cancer. Treatments for cancer such as chemotherapy, radiation therapy, and surgery save lives but can cause other health problems later in life. My team and I want to learn how to deliver the best treatment while reducing these late effects.

I have a particular research focus on histiocytosis (his-tee-oh-sy-toh-sis), a family of rare cancers that affect only a few hundred people each year in the United States. This disease starts when the body makes too many white blood cells called histiocytes. They can build up and form tumors, especially in the bones and skin.

I completed a study which looks at treatment results and health-related quality of life in adults with histiocytosis. This study includes people who are part of Memorial Sloan Kettering Cancer Center’s histiocytosis registry, which collects data from patients from all over the country. We found a strong link between how less pain and fatigue in these patients leads to a better quality of life. We’re hoping to use the data to reach more patients with histiocytosis and improve their quality of life.

I’m now studying how histiocytosis diagnosis and treatment is affected by where a patient lives and what resources they have. This research includes both adults and children with the disease. There are now targeted medications for histiocytosis that are easy to take. We hope more patients will be able to access these treatments and have a better quality of life.

In addition to histiocytosis, I care for young people with leukemia and lymphoma. These illnesses can affect every part of the body, and I enjoy working with different experts who care for these patients as a team. I treat young patients of all ages with these cancers, from infancy through young adulthood.

When I first meet a patient and their family, I let them know that our job is to be there with them throughout this journey. Things may get hard and not always go according to plan. But my job as their physician — and our job as their care team — is to provide support every step of the way.

We help them feel confident that they’re in the right place and meeting with the right people. If the cancer comes back, our experienced team will work together to provide the best care and deliver the best results.
