Professor, School of Integrative Plant Science Plant Breeding and Genetics Section Department of Global Development
Margaret Smith came to Cornell University in 1987 as a faculty member in the College of Agriculture and Life Science’s Department of Plant Breeding and Genetics, focusing on corn breeding. Since August 2020, she has served as the Director of the Cornell Agricultural Experiment Station and Associate Dean of the College of Agriculture and Life Sciences at Cornell. She devotes the other portion of her time to research and extension related to plant breeding.
Margaret’s research is primarily on field corn, but also includes a small amount of work on sweet corn. Her research program emphasizes breeding for productivity and adaptation to New York growing conditions, improving insect and disease resistance, and breeding for organic systems.
Since 2001 Margaret has served as the Extension Leader for Plant Breeding and Genetics, conducting educational programs for agricultural audiences on crop varieties and seeds and talks about plant genetic engineering for a wide range of public audiences. She also oversees the New York Seed Improvement Program, which produces Foundation seed of new Cornell varieties and carries out seed Certification inspections for seed growers.
From 2008 to 2020, Margaret served as the Associate Director for the Cornell Agricultural Experiment Station and from 1998 until 2001, she served as the Associate Director for Cornell Cooperative Extension in the College of Agriculture and Life Sciences. For 15 years, Margaret taught a Cornell course on genetic improvement of crop plants. Before coming to Cornell, Margaret worked in Latin America, first as a plant breeder at the Tropical Agriculture Center for Research and Teaching in Turrialba, Costa Rica, and later as a maize breeder at the International Maize and Wheat Improvement Center in Texcoco, Mexico. The focus of her work in both of these positions was on improving crop varieties for small-scale and subsistence farmers in the tropics – a research interest she maintains to date.
