The Johann Bernoulli Institute for Mathematics and Computer Science comprises two sections: Mathematics and Computer Science. These sections are not separate administrative units but are rather clusters of basic units (basiseenheden) formed around chairs and research programmes: six mathematics research programmes and five computer science research programmes. The set of programmes as a whole has as its main goal performing research at a high international level, leading to publications in international scientific journals and a steady stream of highly qualified researchers (at PhD level). The intended audience consists of the academic research community on one hand and social and professional practice (e.g. industry, hospitals and administration) on the other hand. The Institute aims to provide an attractive research environment for graduate students by maintaining a modern infrastructure and by appointing highly competent and active scientific staff members. The constituting programmes participate in seven graduate schools (onderzoekscholen) and most of the PhD students are enrolled in the educational programmes and take part in other activities offered by these schools.
