As an applicant, you cannot be enrolled as a PhD student until the funding has been secured. There are several ways to finance a PhD programme. For instance, the faculty offers a number of fellowships every year, just as the faculty also admits PhD students who finance the PhD programme themselves.
You can also complete the PhD programme as an Industrial PhD student. An Industrial PhD project is a special, company-oriented PhD project and is carried out over three years between a private or public company, an Industrial PhD student and a university.
