Dr. Kopsell's research program emphasizes cultural, environmental, and genetic influences on the phytonutritional value of vegetable crops. Current research projects have focused on genetic and environmental factors that affect the accumulation of lutein/zeaxanthin and beta-carotene carotenoids in the leafy vegetable crops of kale, spinach, parsley, and basil. Data showing genetic and environmental effects on phytochemical content in vegetable crops is promising and may lead to changes in production practices. Dr. Kopsell's research program includes collaboration with food scientists and nutritionists to help identify bioavailability and impacts of phytonutritionally enhanced crops. Other areas of interest include the enhancement of essential mineral elements (such as Ca, Fe, K, Mg, Se, and Zn) in economically important vegetable crops.
