Jonathan Ellman is the Eugene Higgins Professor of Chemistry and a Professor in the Department of Pharmacology at Yale University. He earned a BS in chemistry from MIT and a PhD in chemistry from Harvard University. He was a postdoctoral fellow in chemical biology at UC Berkeley and in 1992 joined the Department of Chemistry at the same institution. In 1999 he also became affiliated with the Department of Cellular and Molecular Pharmacology at UCSF. He moved to Yale in 2010 where his lab focuses on the development of synthetic methods for the efficient preparation of drug relevant structures that incorporate nitrogen, including numerous C-H functionalization approaches to aromatic and non-aromatic nitrogen heterocycles. His lab also investigates the synthesis, properties, and applications of aza-sulfur compounds, including the development of the chiral amine reagent tert-butanesulfinamide, which has been used for the discovery and production of innumerable clinical candidates and more than ten approved drugs. Most recently he has pioneered a general platform for the asymmetric synthesis of aza-sulfur pharmacophores that are increasingly utilized in drug discovery and development. He is a fellow of the American Academy of Arts and Sciences and the National Academy of Sciences. Awards include the ACS Herbert C. Brown Award for Creative Research in Synthetic Methods, the ACS Award for Creative Work in Synthetic Organic Chemistry, the Pedler Award from the Royal Society of Chemistry, and the Yale Dylan Hixon Prize for Teaching Excellence in the Natural Sciences.
