Ted Whitwell is Interim Director of Coastal Research and Education Center at Charleston beginning July, 2017. He was formerly the Associate Dean for Academic Programs (2009 – 2017) for the College of Agriculture, Forestry, and Life Sciences at Clemson University. Prior to being Associate Dean, he was Chair of the Department of Horticulture at Clemson University for 10 years (1998 to 2008). He continues to teach a Weed Management course and serves on graduate committees.

In 1984, Ted was appointed Associate Professor in the Horticulture Department at Clemson with Weed Science teaching and research responsibilities. Dr. Whitwell has served as the major advisor for about 20 graduate students and served on advisory committees for 45 other graduate students. He has authored or coauthored 90 refereed journal articles and 200 + abstracts and other technical articles.

Ted Whitwell grew up on a small West Tennessee farm where his interest in weed science as a career grew out of his use of herbicides on his father's farm and summer work experience with Giegy Chemical Company. He attended The University of Tennessee at Martin, receiving a B.S. degree in 1972. Ted completed MS and Ph.D. degrees at Oklahoma State University. After completion of graduate school, he worked for seven years as Extension Weed Scientist with Auburn University and was located in North Alabama. He became involved in the newly organized Alabama Weed Science Society by serving as board member, vice president and president. In 1990, He was selected as Southern Weed Science Society Outstanding Young Weed Scientist. The Southern Nursery Association and the South Carolina Nursery Association also honored him for outstanding research accomplishments in 2004. He retired from full time employment in June 2017.
