Pediatrics

I am a pediatric oncologist who specializes in the treatment of children with neuroblastoma. With my colleagues, I am researching and developing innovative immunotherapies for this disease.

Read more

I have a strong research background in immunology that fuels my work both in the lab and with my patients. I am intrigued by the natural power of the immune system to fight disease. We have learned how to harness this power to recognize and fight cancer. Immunotherapies that were pioneered at Memorial Sloan Kettering are now part of the standard of care for children with neuroblastoma.

In my research, my colleagues and I are working to develop new approaches for treating neuroblastoma with antibodies. In one approach, some of a patient’s T cells (white blood cells) are removed and attached to a specific antibody which recognizes neuroblastoma cells. These modified T cells could then be returned to the patient, where they would recruit other T cells in the body to attack and kill neuroblastoma cells. We expect that this approach could be even more effective than the immunotherapies we use today. I hope my research can help bring new therapies into clinical trials and one day soon improve the survival of children with neuroblastoma.

The team of neuroblastoma experts at Memorial Sloan Kettering treats more patients with neuroblastoma than any other institution in the world. We have a shared enthusiasm for learning more about this disease and striving to improve the survival of our patients.

When I meet with the parents of a child with neuroblastoma, I listen carefully to what they have to say. Parents know their children better than anyone, and are vital partners in planning and carrying out a child’s treatment.
