The IRB provides high-level scientific education both for undergraduate students in the form of short stages and experimental diploma thesis, as well as for graduate students. The PhD program is carried out in collaboration with Swiss and foreign universities. The experimental work is carried out at IRB under the direct supervision of a Group Leader. The program includes seminars, lessons, summer courses and an annual retreat. An International Lecture Course is organized every year as part of the IRB International PhD Program in Immunology, Cell Biology and Biochemistry. Lectures are given by visiting experts with international reputations. Currently the IRB has 30 students. Since the beginning of the program more than 60 PhD theses have been successfully defended.
