Most graduate students follow the Ph.D. program, which is completed by a doctor's thesis and takes four additional years. There is, however, also a two-year graduate program leading to a Diploma in Research. The Sterrewacht Leiden offers opportunities for graduate students to work with internationally recognized scientists in a variety of research areas.
Students interact and cooperate with staff members on a direct and personal level.
Strong ties with other national and international research institutes provide fruitful exchange of scientists and ideas. In addition, members of the Sterrewacht Leiden have access to some of the best telescopes and fastest computers available, providing all the necessary means for top level research in both observational and theoretical areas.
