Tom W. Muir received his B.Sc in Chemistry in 1989 and Ph.D. in Chemistry in 1993 from the University of Edinburgh. After postdoctoral studies with Stephen B.H. Kent at the Scripps Research Institute, he joined the faculty at the Rockefeller University in New York City in 1996. In 2011, Dr. Muir joined Princeton University as the Van Zandt Williams, Jr. Class of ’65 Professor of Chemistry. He currently serves as Chair of the Princeton Department of Chemistry. He has published over 200 scientific articles in the area of chemical biology and is best known for developing methods for the preparation of proteins containing unnatural amino acids, posttranslational modifications and spectroscopic probes. These approaches are now widely employed in academia and industry. His currents interests lie in the area of epigenetics, where he tries to illuminate how chemical changes to chromatin are linked to different cellular phenotypes. Professor Muir has won a number of honors for his research, including; the Burroughs-Wellcome Fund New Investigator Award, the Pew Award in the Biomedical Sciences, the Alfred P. Sloan Research Fellow Award, the Leonidas Zervas Award from the European Peptide Society, the Irving Sigal Award from the Protein Society, the Vincent du Vigneaud Award in Peptide Chemistry, the Blavatnik Award from the New York Academy of Sciences, the Jeremy Knowles Award from the Royal Society of Chemistry, the Arthur C. Cope Scholar Award from the American Chemical Society, the Breslow Award in Biomimetic Chemistry from the American Chemical Society, and the E.T. Kaiser Award in Protein Chemistry from the Protein Society. Dr. Muir is a Fellow of American Association for the Advancement of Science, the Royal Society of Chemistry and the Royal Society of Edinburgh.
