As a core modern science, chemistry spans the full spectrum of modern industries and technologies. Both chemists and biochemists are employed in scientific and non-scientific research and applied capacities. The major in chemistry or biochemistry prepares students for graduate school (essential for those interested in a research career); professional schools of engineering as well as medicine, dentistry, and other health-related professions; careers in the chemical and biotechnology industries and in capacities requiring such expertise (such as museum conservation); and secondary school teaching.
