Cameron McCoy worked with I-DROP during spring semester 2018 and is an undergraduate majoring in Crop Sciences with a minor in sustainability. He hails from the far south-side of Chicago. His research interests include soil quality, water quality, and the efficiency of sustainable agriculture. He graduated with a Bachelor of Science degree in May of 2020.

Laura K_20190603 editsLaura Krueger is a senior in Biological and Agricultural Engineering at Kansas State University. She worked with the I-DROP team on a research project as part of a summer internship program through the National Great Rivers Research and Education Center (NGRREC) in 2019.Fernando Zucher_2019

Fernando Zucher started with the I-DROP team at the University of Illinois in April 2019 as a visiting scholar.



Guilherme lab_2Guilherme Rodrigues de Sousa started with the I-DROP team in 2019 as a visiting scholar. He primarily assisted with data collection at the Dudley Smith Farm near Pana, Illinois where the team is studying the agronomic and environmental impacts of cover crops and 4R nitrogen management on tile-drainage nitrate losses.

Mary Foltz started working with the I-DROP team in July 2018 and is advised by Dr. Julie Zilles and Dr. Jeremy Guest. She received received an Illinois Water Resources Center grant with Dr. L. Christianson.



Giovani Preza Fontes started in the lab in May 2017, and was co-advised by Dr. Cameron Pittelkow (UC Davis). His PhD (May 2021) research is focused on evaluating the agronomic and environmental impacts of cover crops and 4R nitrogen management on tile-drainage nitrate losses and soil nitrous oxide emissions in a continuous corn cropping system. Dr. Preza Fontes is now a post doc at Purdue University.

Charles_IDROP fieldCharles Dochoff was an undergraduate in the Agricultural and Biological Engineering program at the University of Illinois who joined I-DROP during summer 2018. He assisted with lab and field activities, as well as creating custom CAD images to better communicate our work.201909_Gabe Johnson_Ksat testing_2

Gabe Johnson, EIT, graduated with a M.S. in the Department of Agricultural and Biological Engineering in summer 2021 and is now pursuing a PhD at Iowa State University. Gabe’s thesis work focused on parameterizing physical properties of woodchips used in denitrifying bioreactors with the goal of improving bioreactor design and performance.
