Profile

Matt spent much of childhood outside exploring the mixed hardwood pine habitats of the South Carolina Lowcountry and developed an appreciation, through family influences, for gardening and biology overall. He earned a B.S. and a M.S. in Biology and Environmental Studies, respectively, from the College of Charleston. While enrolled in graduate school at COFC, he took a job working for the Vegetable Laboratory (USDA ARS) in Charleston and fell in love with Agricultural Research. After a short stint as a Naturalist at a county park, he returned to working in agricultural research at Clemonson Univeristy's Coastal Research and Education Center for the Horticultural Project (alongside supervisor Dr. Brian Ward). Throughout the past 10 years at Clemson, Matt has come to see that the key to excellent agricultural research is synergistic collaboration between different disciplines (Horticulture, Weed Science, Plant Breeding, Pathology, Entymology, and Post-harvest Physiology) all play a critical role in forwarding the agricultural economy of South Carolina.
