PhD Defences

At CWI, we believe that combining different talents creates excellence, so we are careful to nurture and facilitate young researchers from man different backgrounds. We are proud to say that many of the Netherlands' researchers in mathematics and computer science once worked at CWI in their careers.

During their 4 years of research, our PhD students work at CWI, most of the time - or from home, in corona times. As CWI is no university, their PhD defences take place at the university of the main supervisor, often a professor who is a researcher at CWI for 4 or 3 days a week and who is working at a university for 1 or 2 days a week. We collaborate with many Dutch universities (see also Together with universities we tackle major societal challenges).
