For students who have already attained an MSc degree, and are interested in a career in research or education, NU also offers a full range of PhD programs in Science, Engineering, and Technology. The programs are offered jointly by the School of Science and Technology and the School of Engineering; students are able to utilize the laboratory and faculty resources of all departments across both schools. The PhD programs are fully research-based, lasting four years, with students working under the supervision of a faculty advisor and a thesis committee.
