Ronnie Coffman

International Professor of Plant Breeding

Ronnie Coffman serves as the Andrew H. & James S. Tisch Distinguished University Professor and Director of International Programs in the College of Agriculture and Life Sciences at Cornell University. For over 40 years, Dr. Coffman has indefatigably empowered remarkable cadres of people in the pursuit of better lives for people in some of the world’s most populous countries. He has dedicated himself to helping smallholder farmers with scarce resources whose lives are frequently bypassed by agricultural science and innovation.

Dr. Coffman is the vice-chair of the Borlaug Global Rust Initiative, an international consortium of more than 1,000 scientists from hundreds of institutions working together to protect the world’s wheat supplies. The global effort was launched in 2005 in partnership with CIMMYT, ICARDA, FAO and the late Norman E. Borlaug. He is currently principal investigator for a wide-range of international projects focused on food security and global development, including: Delivering Genetic Gain in Wheat and NextGen Cassava. In 2013, he won the inaugural World Agriculture Prize for his achievements guiding scientific and social change across continents and generations. In 2019 he was elected a fellow of the American Association for the Advancement of Science (AAAS) for his distinguished contributions to food security, including innovative research programs, support for women throughout science, and development of worldwide science communication programs.

Dr. Coffman strongly supports gender initiatives that promote professional development for young women scientists. In 2011, he was honored with the Mentoring Award from the Women in Agronomy, Crops, Soil and Environmental Sciences. In 2013, when he won the inaugural World Agriculture Prize, he donated the $50K award to Advancing Women in Agriculture through Research and Education (AWARE), an initiative at Cornell whose members believe that empowering women as an underserved group holds the greatest potential to make significant impacts in agricultural development.

He was also integral in establishing the West Africa Centre for Crop Improvement (WACCI) program in Ghana, a program that educates and trains the next generation of plant breeders for Africa, in Africa. WACCI celebrated its 13th anniversary in 2020.

Previous positions include Associate Dean for Research; Director of the Cornell University Agricultural Experiment Station; Chair of the Department of Plant Breeding and Genetics; and Plant Breeder at the International Rice Research Institute (IRRI). Coffman’s work has been important to the development of improved rice varieties grown on several million hectares throughout the world. He has collaborated extensively with institutions in the developing world and has served as a board member for several international institutes.

Dr. Coffman grew up on a farm in Kentucky, and completed his undergraduate and master’s degrees at the University of Kentucky. His Ph.D. is from Cornell, for which Norman E. Borlaug served on his thesis committee and oversaw his research, and with whom Coffman had a lifelong association.
