Chemists and materials scientists study physical substances at the atomic and molecular levels, and uncover the methodology of chemical reactions. Chemical engineers, on the other hand, apply an interdisciplinary approach, combining chemistry, biology, physics, and math to solve problems in fuel production, drug development, or new food products. As research scientists, they are tasked with the invention of novel chemical processes, and must design equipment for large-scale manufacturing. Further, the increasing demand for lifesaving new drugs will expand opportunities for biochemists. For example, biochemists will be needed to conduct genetic research and to develop new medicines and treatments.
