Professor Walsh is currently the Hamilton Kuhn Professor of Biological Chemistry and Molecular Pharmacology at Harvard Medical School. He is one of the leading enzymologists in the world. He has elucidated the catalytic mechanisms of a wide variety of enzymes including flavoproteins and other redox enzymes. He has also pioneered the design of mechanism-based enzyme inhibitors (or "suicide" substrates). His work has found practical application in the design of antibacterial agents, anticonvulsive agents, plant growth regulators, and antitumor drugs. His current focus is on the biosynthesis and mechanism of action of antibiotics and bacterial siderophores. He has published over 600 scientific articles and his book, Enzymatic Reaction Mechanisms, has educated generations of enzymologists.
Professor Walsh's accomplishments have been recognized through numerous awards which include the Eli Lilly Award in Biochemistry, the Arthur C. Cope Scholar Award in Organic Chemistry, the Repligen Award in Biological Chemistry, and the Alfred Bader Award in Bioorganic and Bioinorganic Chemistry. He is a member of the National Academy of Sciences, the Institute of Medicine, and the American Academy of Arts and Sciences.
