What is the difference between chemistry and chemical engineering?

There is some overlap in the training of chemists and chemical engineers, but they are typically involved in different aspects of the chemical enterprise. Chemists typically are interested in how processes work and developing new understanding of chemical reactions and the structure of chemical materials. In industry, chemists typically work in developing new or improved materials. Chemical engineers tend to focus on the process by which chemical materials are produced. In industry, chemical engineers typically focus on developing efficient processes for manufacturing chemicals. Thus, engineers tend to focus on optimizing processes, while chemists work to develop new processes.  A dual chemistry/chemical and biological engineering degree program is offered for students interested in both fields.
