The goal of a PhD degree in computer science is to gain deeper knowledge of some sub-field of computer science and the ability to attain new scientific insights in it. PhD studies are usually based on the MSc degree, on the topic of the Master's thesis. We try to steer MSc students who seem like promising PhDs towards such subjects that will make a good basis for PhD studies.
A great part of the PhD students belong to some graduate school. The graduate schools organise PhD courses, and offer some positions for full-time PhD researchers. The department participates in four PhD schools and a large network of graduate schools. It is also possible to fund your PhD studies by working in one of the department's research projects or as a teacher. Furthermore, it is possible to carry out your PhD studies alongside a research and development job at an IT company or research institution, although this kind of arrangement has proven to be very strenuous.
Doing PhD studies is a full-time job. Before you apply to become a PhD student, please ask yourself if you are committed to four years of full-time studies and research.
