Higher Education

IML-CZO is a collaboration between a number of universities, including the University of Iowa, the University of Illinois Urbana-Champaign, Iowa State University (Department of Agronomy in cooperation with the Comparison of Biofuels Systems [COBS] site), the University of Tennessee-Knoxville, the University of Minnesota, and the University of Nebraska-Omaha (among others). Students and faculty at these universities are working together to better understand the processes and science of the IML-CZO.

In addition, the IML-CZO is part of a Research Experiences for Undergraduates NSF proposal  through the Department of Geographical and Sustainability Sciences to further enhance student participation in this research.
