DoKyoung Lee

Director of Online Programs

Dr. Lee improves perennial grass production systems for sustainable biomass and bioenergy feedstocks. His research focuses on increasing genetic and abiotic stress tolerances of perennial grasses. He finds new ways to integrate perennial grasses into row cropping systems to improve sustainability, ecosystem services, and water quality.
