John Monnier is Professor of Chemical Engineering at the University of South Carolina since 2004 after retirement from 32 years in industry with Eastman Kodak and Eastman Chemical Research Laboratories. He has spent his career in the field of heterogeneous catalysis and in one area, the epoxidation of higher olefins, discovered a catalyst and kinetic process for the selective epoxidation of butadiene to 3,4-epoxybutene using gas phase O2, representing the first advancement in more than 50 years for olefin epoxidation. This new epoxide represented a novel and versatile precursor for hundreds of new chemicals. His work has been recognized by the C. E. K. Mees Award from the Scientific Council of Kodak Research Laboratories, the 1998 Outstanding Industrial Innovator Award by the American Chemical Society, the 2000 Herman Pines Award from the Chicago Catalysis Club, and the 2002 F. C. Ciapetta Lectureship in Catalysis by the North American Catalysis Society. In 2017, he was elected to the National Academy of Engineering. His current research interests are in the areas of bimetallic catalyst synthesis and subsequent evaluation for a wide range of applications. Professor Monnier has published 101 journal articles in the field of catalysis and been awarded 32 US patents.
