Biological systems engineering or biosystems engineering is a broad-based engineering discipline with particular emphasis on biology and chemistry. It can be thought of as a subset of the broader notion of biological engineering, though not in the respects that pertain to biomedical engineering as biosystems engineering tends to focus less on medical applications than on agriculture, ecosystems, and food science. It involves aspects of genetic engineering, particularly regarding the agricultural applications. The discipline focuses broadly on environmentally sound and sustainable engineering solutions to meet societies’ ecologically-related needs. Biosystems engineering integrates the expertise of fundamental engineering fields with expertise from non-engineering disciplines.
