High Quality Content by WIKIPEDIA articles! Biological Systems Engineering (BSE) 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. It is not to be confused with Biomedical Engineering as it tends to focus less on medical applications than on agriculture, ecosystems, and food science. It is not necessarily genetic engineering, although that can be a major aspect (particularly for its agricultural applications). The discipline focuses on environmentally sound and sustainable engineering solutions to meet societies’ ecologically related needs. Biological systems engineering is a broad and growing engineering field that integrates the expertise of fundamental engineering fields with expertise from non-engineering disciplines.
