Frederick Alt

Frederick W. Alt is an American geneticist. He is a member of the Immunology section of the National Academy of Sciences and a Charles A. Janeway Professor of Pediatrics, and Professor of Genetics at Harvard Medical School. He is the Director of the Program in Cellular and Molecular Medicine at the Boston Children's Hospital. He is a Howard Hughes Medical Institute investigator since 1987.
He completed his undergraduate studies at Brandeis University, graduating in 1971, and then went on to earn a Ph.D. in Biology from Stanford University in 1977 while under the research direction of Robert Schimke. He performed his postdoctoral work in David Baltimore's laboratory at MIT. From 1982-91 he was on the faculty at Columbia University and then moved to Harvard Medical School.
His research interest is in maintenance of genome stability in cells of the mammalian immunological system, particularly antigen receptor variable region gene assembly in developing B and T lymphocytes, immunoglobulin heavy chain class switch recombination (CSR), and somatic hypermutation in activated mature B lymphocytes.
