Chemical engineering is a branch of engineering that applies physical sciences (physics and chemistry
), life sciences (micro biology and biochemistry), together with applied mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy. A chemical engineer designs large-scale processes that convert chemicals, raw materials, living cells, microorganisms and energy into useful forms and products. Advancements in computer science found applications designing and managing plants, simplifying calculations and drawings that previously had to be done manually. The completion of the Human Genome Project is also seen as a major development, not only advancing chemical engineering but genetic engineering and genomics as well. Chemical engineering
principles were used to produce DNA sequences in large quantities. Using engineering's own analytical and synthetic methodologies and also its traditional sensitivity to the cost and practicality of the solution (s) arrived. Industrial bio-engineering extends from the creation of artificial organs by technical means or finds ways of growing organs and tissues through the methods of regenerative medicine to compensate reduced or lost physiological functions (Biomedical Engineering) and to develop genetically modified organisms, i.e., agricultural plants and animals as well as the molecular designs of compounds with desired properties (protein engineering, engineering enzymology). In the non-medical aspects of bio-engineering, it is closely related to biotechnology, nanotechnology.
