Dr. Juan Arbelaez

Assistant professor- International plant breeding

Dr. Juan Arbelaez is a plant breeder and geneticist who is passionate about reducing hunger, malnutrition, and poverty around the world. In pursuit of this passion, Juan is focusing on a) developing varieties of spring oat (Avena sativa) and rice (Oryza sativa) with enhanced nutritional quality, b) helping breeders around the world develop and implement cost-effective breeding methods and tools to accelerate breeding for multiple traits including yield and grain quality, and c) developing cover crop oat varieties for the Midwest to help protect life-sustaining natural resources.

Dr. Juan Arbelaez began his career at the International Center for Tropical Agriculture (CIAT) in Cali, Colombia where he worked on developing novel rice germplasm with introgressions from wild rice species to support the global rice community. Juan then went on to do a Ph.D. and a post-doc in Dr. Susan McCouch’s rice genetics lab at Cornell University where he worked on understanding the genetic bases of tolerance to aluminum and iron toxicity, which are critical abiotic stresses affecting rice production in parts of South America and Africa. Prior to joining the University of Illinois, Juan was a rice breeder at the International Rice Research Institute (IRRI), headquartered in the Philippines, where he played a critical role in the development and deployment of a global genomic selection strategy to accelerate rice improvement in irrigated environments across Southeast Asia and West Africa.

Dr. Jessica Rutkoski

Assistant Professor- Small grains breeding

Dr. Jessica Rutkoski is a small grains breeder and a quantitative geneticist with a passion for putting the principles and techniques of quantitative genetics and statistics to use in applied breeding in order to accelerate rates of genetic gain in ways that benefit people and the environment. Jessica’s main goals are to a) develop winter wheat (Triticum aestivum L.) varieties that will help improve the profitability of wheat production in Illinois and surrounding states, b) improve levels of quantitative disease resistance in small grains, and c) develop and deploy new breeding methods to accelerate rates of genetic gain in wheat and other self-pollinated crops.

Dr. Jessica Rutkoski received her Bachelor’s of Science degree in Genetics from the University of Wisconsin-Madison in 2009 and then went on to get her Ph.D. at Cornell University under the direction of Small Grains Breeder Dr. Mark Sorrells.  In 2014, Jessica completed her Ph.D. and then continued on at Cornell University as an assistant professor where her mission was to innovate and transfer advanced breeding methods like genomic selection to wheat breeding programs globally. In doing so, Jessica conducted her research in collaboration with the International Maize and Wheat Improvement Center (CIMMYT), headquartered in Mexico, where she worked as an Adjunct Associate Scientist in the Global Wheat Breeding Program. In pursuit of new challenges and broader impact, in 2016, Dr. Rutkoski began working as a Scientist in the plant breeding division at the International Rice Research Institute (IRRI), located in the Philippines. Jessica’s role at IRRI was to improve rice breeding efficiency through more effective use of data and analytical techniques.
