In recent years there have been other institutes loosely based on the Princeton original, in some cases established with help from IAS professors. In 1997 IAS professor Chen-Ning Yang helped the Chinese set up the Institute for Advanced Study at Tsinghua University in Beijing. The Freiburg Institute for Advanced Studies in Freiburg, Germany was founded in 2007, with IAS director at the time Peter Goddard giving the inaugural address. Princeton IAS professors André Weil and Armand Borel helped to establish close contacts with the Ramanujan Institute for Advanced Study in Mathematics, founded in 1967 as part of the University of Madras in India.
