Current Students:
Eric Wilkening (M.S. student)
Raised in Omaha, Nebraska, Eric Wilkening’s roots in agriculture are strong as he is the 7th generation at his family’s farm near Arlington, NE. Following the completion of his bachelor’s degree in Agricultural Engineering at the University of Nebraska-Lincoln, he is pursuing a master’s degree in the same field. As an undergraduate, Eric worked on multiple irrigation research projects with topics ranging from system performance to advanced scheduling techniques. With interests in water resource conservation, irrigation system performance, and extension outreach programs, Eric’s graduate research is involving the in-field implementation and performance analysis of models combining irrigation and fertigation management under the advisement of Dr. Derek Heeren. You can read about one of Eric's projects here.
Jamie Duan (Ph.D. student)
I received my bachelor’s degree in Irrigation and Drainage Engineering at Hohai University, Nanjing, China. I had a deep recognition of the worldwide water shortage and pollution from my undergraduate study, which inspired my determination to continue research of hydrology and water resource as a master's student. I did my master’s degree at Texas A&M University, where I participated in ecohydrology research. My master’s thesis was “Influence of land-use change and agriculture practices on water, carbon, and energy fluxes.” However, many problems that appeared in my graduate research told me that I should dive deeper into research to get to the solutions. I received an opportunity to pursue a Ph.D. in Biological Engineering at the University of Nebraska-Lincoln, where I am now co-advised by Dr. Daran Rudnick and Dr. Derek Heeren.
Suhib Hamid (M.S. student)
I earned my bachelor’s degree in Agriculture in 2016 from the University of Khartoum, Sudan. After my graduation, I worked as a lab assistant at the soil laboratory at the University of Khartoum (2016 – 2017). Through this year I gained a lot of knowledge about soil, water, and plant analysis. I’m very interested in technology and using GIS, remote sensing, and mapping in soil analysis. Since 2017 I have been working for Zadna, a company that is interested in establishing and developing agricultural projects specialized in horticultural, animal, and crop production. During this period, I implemented the soil surveys for most of the Zadna agricultural projects in different locations across Sudan. I received an opportunity to pursue an M.S. in Mechanized Systems Management, in the department of Biological Systems Engineering at the University of Nebraska-Lincoln, under the supervision of Dr. Derek Heeren.
Hakam Almagzoop (M.S. student)
I completed my undergraduate degree in Forestry Science from the University of Khartoum (Sudan). I am working for Zadna, a company that is interested in establishing and developing agricultural projects specialized in horticultural and animal production and crop production. I implemented and followed up on various horticultural projects in different locations in Sudan. In recent years, Zadna focused on importing center pivot irrigation systems from Valmont Industries (Omaha, NE) to contribute to the development of irrigation systems used, the preservation of water resources, and the utilization of the vast arable lands in Sudan. I am starting a master's degree in Mechanized Systems Management in the BSE department at the University of Nebraska-Lincoln under the supervision of Dr. Heeren.
