Since Nordita's establishment in 1957 the original focus on research in atomic and nuclear physics has been broadened. Research carried out by Nordita's academic staff presently includes astrophysics,

. The in-house research forms the backbone of Nordita activities and complements the more service oriented functions. By mission, Nordita has the task of facilitating interactions between physicists in the Nordic countries as well as with the international community; therefore the comparably small institute has a large number of visitors, conferences and scientific programs that last several weeks. Notable former or present researchers at Nordita include Alexander V. Balatsky,

Organization

Nordita is governed by a board consisting of one representative and one alternate member from each Nordic country, headed by a chair person. The board appoints a number of research committees which evaluate proposals and advice the board on scientific and educational matters. The Nordita board nominates a director who is appointed by the president of

and the vice-chancellor of Stockholm University. The director, currently Niels Obers, is responsible for the day-to-day administration of the institute and provides scientific leadership.

Funding

Nordita is funded jointly by the Nordic countries via the
