Bioengineering is a field rooted in physics, mathematics, chemistry, biology, and the life sciences. Each of these areas is applied in a systematic, quantitative, and integrative way to approach problems important in biology, biosystems, medical research, and clinical practice. Bioengineering advances fundamental concepts, creates knowledge from the molecular to organ to system levels, and develops innovative processes for the prevention, diagnosis, and treatment of disease. In short, bioengineering seeks to improve the health and life of humankind on many levels.
