Overview
The mission of the Department of Biological Systems Engineering (BSE) is to develop and disseminate engineering knowledge and practices that protect natural resources and improve sustainable production, processing, and utilization of biological materials.
The teaching program in BSE offers engineering B.S., M.S., and Ph.D. programs for students enrolled in the College of Engineering and service courses for students enrolled in the College of Agriculture and Life Sciences and other colleges. The degree programs in BSE are administered by the College of Engineering; therefore, the curriculum and courses offered for the B.S. in biological systems engineering are listed in the College of Engineering section of this catalog. Students interested in pursuing an undergraduate degree program in Biological Systems Engineering must first be admitted to the College of Engineering.
Service courses designed to meet the needs of students enrolled in different programs in CALS are listed in the following section. These courses generally are not taken to meet engineering degree requirements except as free electives.
