Chemical engineering is a branch of engineering that uses principles of chemistry, physics, mathematics, biology, and economics to efficiently use, produce, design, transport and transform energy and materials.. Chemical engineers typically hold a degree in Chemical Engineering or Process Engineering. In broad terms, chemical engineers conceive and design processes to produce, transform and transport materials beginning with experimentation in the laboratory followed by implementation of the technology in full-scale production. Chemical engineers are in great demand because of the large number of industries that depend on the synthesis and processing of chemicals and materials. In addition to traditional careers in the chemical, energy and oil industries, chemical engineers enjoy increasing opportunities in biotechnology, pharmaceuticals, electronic device fabrication and environmental engineering. The unique training of the chemical engineer becomes essential in these areas when processes involve the chemical or physical transformation of matter.
