Miembros Dan R. Littman, MD, PhD New York University Medical Center New York, NY Dr. Dan R. Littman is the Helen L. and Martin S. Kimmel Professor of Molecular Immunology and a professor of pathology and microbiology in the Skirball Institute for Biomedical Research at the New York University Medical Center, as well as an investigator of the Howard Hughes Medical Institute. Dr. Littman has made many important contributions to our knowledge of the immune system, including how it interacts with the HIV virus as well as the bacteria in our bodies. He’s also greatly advanced our understanding of T cell differentiation, especially Th17 cells, discovering a key regulator of their activity as well as how bacteria influence their development. For these efforts, he was honored with the 2016 William B. Coley Award for Distinguished Research in Basic Immunology and was elected to the National Academy of Sciences and the National Academy of Medicine. His current work continues to explore the complex relationship between our immune system and bacteria and how it influences our health.
