Aerospace engineering: Aerospace engineers explore the knowledge of interdisciplinary subjects such as computer science, physics, and maths to design, build, and test machines that can fly. Aeronautical engineers focus on aircraft, and astronautical engineers focus on spacecraft.
Chemical engineering: Chemical engineering involves developing and applying chemical substances (or products), usually in industrial quantities.
Engineering Management: You could also study one of the above branches of engineering with management. Engineering Management is an interdisciplinary field. Courses in these programs combine industrial engineering skills and business expertise.
