The Department of Biosystems and Agricultural Engineering is administered jointly by the College of Agricultural Sciences and Natural Resources and the College of Engineering, Architecture and Technology. Biosystems engineering courses integrate engineering sciences, physical sciences, and biological sciences and teach students to address real-world challenges. With the guidance of experienced faculty, students work both as individuals and in teams to design creative solutions to complex problems. The program culminates in a senior year design course in which students integrate the analysis, synthesis and other abilities they have developed throughout the earlier portions of their study into a capstone experience.
