Roger Sheldon is a recognised authority on Green Chemistry and Catalysis and Professor Emeritus of Biocatalysis and Organic Chemistry at Delft University of Technology. He is the author of several books on the subject of catalysis as well as ca. 400 professional papers and >40 granted patents.

Recently, he co-authored, with his coworkers Isabel Arends and Ulf Hanefeld, a book on “Green Chemistry & Catalysis”. He is widely known for developing the concept of E factors for assessing the environmental footprint of chemical processes. His research interests are in the general area of Green Chemistry and Catalysis, encompassing the application of homogeneous, heterogeneous catalysis, and biocatalysis in organic synthesis.

He received a Ph.D. in organic chemistry from the University of Leicester (UK) in 1967. Prior to joining Delft University, in 1991, he had more than 20 years industrial experience, as Vice President for Research and Development at DSM / Andeno from 1980 to 1990 and with Shell Research Amsterdam from 1969 to 1980. He is also CEO of CLEA Technologies, a start-up biotech company.
