2025 Roscoe Ellis, Jr. Lecture to Feature Soil Scientist, Dr. Alexandra Kravchenko
The Department of Agronomy is excited to announce Dr. Alexandra Kravchenko as the 2025 Roscoe Ellis, Jr. Lecturer. A leading researcher in soil physics, spatial analysis, and soil biogeochemistry, Dr. Kravchenko has spent more than 20 years advancing understanding of how soil structure, management practices, and environmental conditions influence carbon storage and greenhouse gas emissions.
Dr. Kravchenko will deliver her lecture, “Soil Pores as Habitats for Microorganisms,” on Tuesday, September 16, at 4:00 p.m. in the Regnier Forum, Regnier Hall. Refreshments will be served at 3:30 p.m. in the Regnier Atrium. The lecture will also be available via Zoom at https://ksu.zoom.us/j/99472904098?pwd=Sk96rpPMYibG3zfLBpLydbBNaNoJNh.1 (Zoom meeting ID: 994 7290 4098 Passcode: 453066).
Internationally recognized for her pioneering work in soil carbon and nitrogen cycling, Dr. Kravchenko has developed new approaches in geostatistics, multifractal analysis, and power analysis that have shaped how scientists study spatial variability in soils and agricultural systems. She has led major interdisciplinary projects, including long-term conservation research at Michigan State University’s Kellogg Biological Station and collaborative work with the Great Lakes Bioenergy Research Center.
Beyond her research, Dr. Kravchenko is a dedicated mentor and educator. She has trained graduate students and postdoctoral scholars, taught advanced statistical methods, and co-coordinated MSU’s Statistical Consulting Center. She also leads award-winning public outreach efforts, creating exhibits and multimedia experiences that make soil science accessible and engaging to thousands of learners.
The Roscoe Ellis, Jr. Lectureship was established to advance soil science at Kansas State University by bringing prominent scholars to interact with students and faculty. The lectures honor the career of Dr. Roscoe Ellis, Jr., and commemorate his many years of outstanding service to students, the university, and the soil science community. His dedication, knowledge, and helpfulness influenced generations of scientists in their educational and professional pursuits. Donations by family, friends, and colleagues endowed the Lectureship Fund with the Kansas State University Foundation, and ongoing support is needed to help sustain this annual event. Contributions are welcome and can be sent to the Roscoe Ellis Lectureship, Department of Agronomy, 2004 Throckmorton Hall, Kansas State University, Manhattan, KS, 66506.
