Chemical engineering deals with design, development and operations of mechanisms, machines and plants for chemical, physical and biological reactions and processes. Working at the interface of molecular sciences and applied engineering, chemical engineering helps brings research and innovations from laboratories to the industry and society. Almost every aspect of our daily life is now dependent on products and services of the chemical industry.

Moreover, the elemental nature of the chemical engineering principles and tools allow chemical engineers to serve the role of "universal engineers" spearheading developments in nanotechnology, advanced materials, fuel and energy, consumer and food products, biotechnology and pharmaceuticals as well as environmental engineering. Not surprisingly, chemical engineers form a large workforce in the industry, academia, consulting, medicine, and other fields. Various global companies hire and have been headed by chemical engineers.
