Biography
Stephen O. Duke received his Ph.D. in plant science from Duke University in 1975. He was Director of the Southern Weed Science Laboratory of ARS from 1987 until1996 and was Research Leader of the Natural Products Utilization Research Unit in Oxford, Mississippi from 1996-2000. He became a Principal Scientist at the National Center for Natural Products Research of the School of Pharmacy, Univ. Mississippi in 2021. He is best known for his research on herbicide modes of action and natural products for weed management. He has over 500 peer-reviewed publications that have resulted in Web of Science and Google Scholar h-indices of 75 and 108, respectively. He has been editor or co-editor of 11 books and co-author a textbook. He has been President of the Weed Science Society of America, the International Allelopathy Society, and the International Weed Science Society, as well as Chair of the Agrochemical Division of the American Chemical Society (ACS). He is a Fellow of ACS and the American Association for the Advancement of Science.
