Today’s integrated human and environmental systems means that the civilization engineer must not only create the infrastructure of society but also understand the ecosystems upon which society depends. Dr. Czuba works to better understand Earth-surface processes with the hope that through this understanding we, as a society, can better manage our environment as good stewards of Earth, allowing ecosystems to flourish and our civilization to endure.
Toward this end, he performs fundamental, quantitative research on physical processes in rivers, their linkages to water quality, nutrients, vegetation, and biota, and their response to climate and human forcing at the water, food, and energy nexus. His work spans spatial timescales from entire watershed to specific reaches to local features (e.g., bend, bar, bedform) utilizing theory, modeling, and field measurements, ultimately to better inform river-basin management.
Dr. Czuba’s work focuses primarily on water and sediment transport processes in rivers. His work also extends to nutrient transport on river networks, flow-sediment influences on biota, flow-vegetation-sediment interactions, and microplastics in freshwater systems.
Dr. Czuba is an Assistant Professor of Watershed Engineering in the Department of Biological Systems Engineering. Previously, he was a Post-Doctoral Research Fellow in the Department of Earth and Atmospheric Sciences at Indiana University, Bloomington. He earned his Ph.D. in Civil Engineering from the University of Minnesota, Twin Cities during which time he was the recipient of an Interdisciplinary Doctoral Fellowship, Edward Silberman Fellowship, and Alvin G. Anderson Award. Dr. Czuba also has a M.S. and B.S. in Civil Engineering from the University of Illinois at Urbana-Champaign, and over 5 years of experience working for the U.S. Geological Survey in Illinois and Washington State.
