Kevin is a plant breeder trained at the University of Florida and Iowa State University. For nearly 30 years he has worked on food and nutrition security issues across low- and middle-income countries of Africa, Asia and Latin America, while living in Mexico and Zimbabwe. He is currently directing the genetic resources program at CIMMYT, where more than 180,000 maize and wheat seed collections are maintained and distributed to scientists worldwide for use in addressing the needs of humankind. Biodiversity, including these seed collections, are the ‘raw material’ for all improved crop varieties. His research interests include the use of biodiversity to develop varieties that contribute to environmental sustainability and nutritional output of farming systems. He is also adjunct faculty at the University of Wisconsin, where he teaches about the links between agriculture, nutrition, health and poverty or wealth.
