At Leibniz University Hannover, there are currently 27,000 students studying in nine faculties, and some 3,100 researchers working in more than 180 institutes. The main building of the university is the Royal Palace Welfenschloss at the Welfengarten. Our internationally visible core research topics are in mechanical engineering, in quantum optics and gravitational physics, in biomedical research and in teacher training. The broad range of subjects at Leibniz University is entirely compatible with an overall university strategy of raising its profile, in particular of teaching and research, including the establishment and enhancement of research priority areas originating in the humanities and social sciences. Cooperation agreements with national and international partners strengthen our scientific expertise. By adopting the name of the polymath Gottfried Wilhelm Leibniz in 2006, the university committed itself to unity in its diversity.
