Chapple, Clint C. S.


Dr. Clinton Chapple is the Department Head and a Distinguished Professor of Biochemistry at Purdue University. He earned a B.S. and M.S. in Botany and a Ph.D. in Chemistry from the University of Guelph. Dr. Chapple has received numerous awards, including the Herbert Newby McCoy Award, the Outstanding Undergraduate Teacher Award, selected as a Purdue University Faculty Scholar, and elected a Fellow of the American Association for the Advancement of Science, to name a few. Dr. Chapple's research focuses on biochemistry and molecular biology of plant secondary metabolism. More specifically, understanding and manipulating a compound in cell walls called lignin that contributes to plants' structural strength, but which hinders conversion of plants into other materials and additional ways to alter lignin so that cellulose from plants, such as poplar trees, can be used for ethanol production to provide alternative transportation fuels.
