Chemical Engineering These engineers’ efforts are on the molecular level. They don’t always work directly with chemicals, but they do need a strong background and understanding of them. A lot of chemical engineers work in a lab and use a computer. Chemical engineers use their knowledge of chemistry, engineering, mathematics, and physics to help companies manufacture chemicals, drugs, food, fuel, and many other products that people use every day. Others work in the life sciences, environmental protection, and biotechnology. Biochemical engineers are interested in the human body and do research in the medical field. Some engineers help invent or improve machines that diagnose and treat patients. Others create new medicines to fight disease. Their inventions help doctors take better care of people. If you like to help people, this is one way to do it!
