Jonathan Schneck is a professor of pathology, medicine and oncology at the Johns Hopkins University School of Medicine and a member of the Johns Hopkins Kimmel Cancer Center. His research focuses on T cell immunology. His team pioneered the development of artificial white blood cells, called artificial antigen-presenting cells (aAPCs), which show promise in training animals’ immune systems to fight diseases such as cancer. Using nano-aAPCs, his team recently trained the immune systems of mice to fight melanoma. His lab’s current projects include studying the biophysical, genetic and environmental control of T cell receptor organization. Schneck received his undergraduate degree from Yeshiva University. He earned his M.D.-Ph.D. in immunology from the Albert Einstein College of Medicine. After completing his degree, he trained in pediatrics at the Children’s Hospital National Medical Center in Washington, D.C. From there he worked on the medical staff of the National Institute of Allergy and Immunology at the NIH in Bethesda, and did his postdoctoral training at the Laboratory of Immunology. He joined the Johns Hopkins faculty in 1990 as a junior faculty member.
