Bioengineering as a defined field is relatively new, although attempts to solve biological problems have persisted throughout history. Recently, the practice of bioengineering has expanded beyond large-scale efforts like prosthetics and hospital equipment to include engineering at the molecular and cellular level – with applications in energy and the environment as well as healthcare. A very broad area of study, bioengineering can include elements of electrical and mechanical engineering, computer science, materials, chemistry and biology. This breadth allows students and faculty to specialize in their areas of interest and collaborate widely with researchers in allied fields.
