A Chemical Engineer designs, develops, and optimizes chemical production processes to transform raw materials into valuable and useful products, such as fuels, chemicals, food, pharmaceuticals, and others. They also oversee the operation of chemical production facilities, ensuring that processes run efficiently and safely, and make modifications as necessary. They may also conduct research and development to create new processes and products, using mathematical modeling and computer simulations to evaluate potential performance. Additionally, Chemical Engineers ensure that the production processes comply with environmental regulations and safety standards, and work to minimize waste and improve sustainability. Overall, a Chemical Engineer applies their knowledge of chemistry, biology, physics, and math to solve problems and improve the production of various products.
