Biography

Dr. Romulo P. Lollato got his B.S. degree in Agronomy from Londrina State University (Brazil), M.S. in Plant and Soil Sciences from Oklahoma State University (OSU), and Ph.D. in Crop Science from OSU. Currently, Romulo is an assistant professor of Agronomy at Kansas State University, Extension Wheat and Forages Specialist, where he provides leadership for an interdisciplinary team developing a strong Extension (80%) and applied research (20%) programs. He is an associate editor for Agronomy Journal, where he received an award for outstanding associated editor in January 2018, and he is a reviewer for Agricultural and Forest Meteorology, Agronomy Journal, Crop Science, Crop and Pasture Science, among other scientific journals. Romulo is a member of the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America.

Romulo’s interest in wheat first started as actual crop production, working in his family’s soybean-corn-wheat farming operation, in which he grew up helping. His interest in wheat increased during his MS, with a thesis focused on wheat response to liming acidic soils in central Oklahoma. During his PhD, his dissertation focused on intensive wheat management and the meteorological limits to winter wheat productivity in the southern Great Plains, as well as soil water dynamics under the wheat crop and wheat variety response to soil pH and aluminum concentration gradients. Currently, Romulo directly oversees over 20 different research projects related to wheat production or applied wheat physiology, most pertaining to M.S. thesis or Ph.D. dissertations of students training in his program.
