Biological systems engineering combines biology, chemistry, and engineering to solve problems associated with environmental protection, conservation of natural resources, the environmentally sound production of renewable resources, and the conversion of these resources to food and non-food products. The curriculum differs from other engineering programs in its focus on natural resources and biological materials. Students may specialize in one of two department options: land and water resources engineering or bioprocess engineering. The land and water resources engineering option is designed for those interested in environmental protection and management. The bioprocess engineering option prepares graduates for the design and development of processes for environmentally responsible manufacturing of bioenergy and value-added products such as food, pharmaceuticals, polymers, and non-biological materials. Students can also use the 18 credit hours of electives in the curriculum for pre-medical/dental and pre-veterinary programs.
