High Quality Content by WIKIPEDIA articles! Biological systems engineering is a broad-based engineering discipline with additional emphasis on biology and chemistry. It is not to be confused with biomedical engineering and it is not necessarily genetic engineering, although the line between the two is sometimes blurred. The discipline focuses on environmentally sound, sustainable engineering solutions to meet societies 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.
