The most common sub-disciplines in engineering include civil engineering and chemical engineering but also include the following disciplines as well that have their own emphasizes and professional associations. Some of the sub-disciplines in engineering are: environmental engineering / materials engineering / mechanical engineering / mechanical and aerospace engineering / mechanical and material engineering / mechanical and space engineering / mechatronic engineering / minerals processing engineering / mining engineering / software engineering / software systems and aerospace engineering / chemical engineering. So there are many sub-disciplines in engineering for an international student to specialise in and make a contribution too.
