Dr. Tony J. Vyn, Professor of Agronomy and Corteva Agriscience Henry A. Wallace Chair in Crop Sciences. Tony has studied crop rotation and tillage systems for his whole career, first at the University of Guelph in Ontario, Canada, and then at Purdue University since 1998. For the past 25 years, Tony has directed Purdue’s long-term tillage plots that were started in 1975 by previous faculty at Purdue. Together with many graduate students and research team members, Tony has investigated the applications and challenges involved in adopting more sustainable cropping systems. He has always been interested in getting to a better understanding corn physiology and nutrient efficiency changes with modern genetics and new management approaches. Tony plans to retire at the end of 2023.

Sotirios Archontoulis is a professor of integrated cropping systems at the Department of Agronomy, Iowa State University. His research aims to predict impacts (e.g. climate change), explain causes (e.g. high/low yields), and design future strategies to improve crop productivity and environmental sustainability. His approach combines field experimentation with process-based simulation models to understand Genotype x Environment x Management interactions and enable prediction at scale.
