Walter Suza: Suza is an Adjunct Associate Professor at Iowa State University. He teaches courses on Genetics and Crop Physiology in the Department of Agronomy. In addition to co-developing courses for the ISU Distance MS in Plant Breeding Program, Suza also served as the director of Plant Breeding e-Learning in Africa Program ​(PBEA) for 8 years. With PBEA, Suza helped provide access to open educational resources on topics related to the genetic improvement of crops. His research is on the metabolism and physiology of plant sterols. Suza holds a Ph.D. in the plant sciences area (with emphasis in molecular physiology) from the University of Nebraska-Lincoln.

Kendall Lamkey: Lamkey is the Associate Dean for Facilities and Operations for the College of Agriculture and Life Sciences at Iowa State University. He works in collaboration with the dean, associate deans, department chairs, college-level centers, and other unit leaders to ensure that operations directly advance the mission of the college and that resources are deployed wisely and efficiently. Previously, he served as the chair for the Department of Agronomy at Iowa State University, where, in addition to advocating for research and the PBEA program, he oversaw the Agronomy Department’s educational direction, its faculty, and Agronomy Extension and Outreach. Dr. Lamkey is a corn breeder and quantitative geneticist and conducts research on the quantitative genetics of selection response, inbreeding depression, and heterosis. He holds a Ph.D. in plant breeding from Iowa State University and a master’s in plant breeding from the University of Illinois. Lamkey is a fellow of the American Society of Agronomy and the Crop Science Society of America and has served as an associate editor, technical editor, and editor for Crop Science.
