David A. Hafler

David A. Hafler (born 1952) is an American neurologist. He is the Edgerly Professor and former chairman of the department of Neurology at the Yale School of Medicine, where he works on immunity, genetics, and multiple sclerosis. In 2018, he was elected to the National Academy of Medicine.

Early life and education Hafler was born in 1952 in New York. He became interested in immunology at a young age and began doing research in the field as a high school student. In 1974 he graduated from Emory University in Atlanta, Georgia with a combined Bachelor of Science in chemistry and Master of Science in biochemistry. His master's thesis was on fragments of myelin basic protein.

In 1978, he received his MD degree from the University of Miami School of Medicine in Miami, Florida. He was a medical intern from 1978–1979 at the Johns Hopkins Hospital in Baltimore, Maryland. From 1979 to 1982, he was a resident in neurology at the New York Hospital-Cornell Medical Center and Memorial Sloan Kettering Cancer Institute in New York City. In 1982, he was a guest investigator in the laboratory of the immunologist Henry G. Kunkel at Rockefeller University. The company went public in 1993 with Henri Termeer and others on the Board of Directors.

In 2000, he was appointed to an endowed professorship and became the Breakstone Professor of Neurology at Harvard.

In 2015, Hafler was appointed to the newly created Edgerly Professorship in Neurology at Yale. This endowed professorship was provided by William S. and Lois Stiles Edgerly who had long supported research in multiple sclerosis. In 2018 he was elected to membership in the National Academy of Medicine with the citation "For seminal discoveries defining the pathogenesis of multiple sclerosis (MS), including identification of autoreactive T cells and mechanisms that underlie their dysregulation, and the discovery of susceptibility genes that lead to MS."
