With more than 9,000 employees and an annual budget of about EUR 900 million, Karlsruhe Institute of Technology (KIT) is one of the biggest public research and education institutions in Germany (25000 students, 4900 researchers/teaching staff). It offers a wide range of degree programs covering Natural Sciences, Engineering, Education, Social Sciences, Arts programs (43 bachelor and consecutive 37 master degrees in 2018). KIT’s doctoral programs offer the opportunity to pursue a doctorate as part of a research program and a structured qualification concept. About 40 of doctoral programs, graduate schools, research training groups, and PhD research groups –funded from national and EU sources- are opened for young scientists from all over the world. As in the previous years, the results in various rankings in 2017 show that KIT is very well positioned in national and international comparisons. For example, in the "QS World University Rankings," the overall ranking of the best universities in the world published by Quacquarelli Symonds Ltd. in London, the KIT ranked 107^th in 2017. The group is located at the Institute of Nanotechnology (INT) KIT (http://www.int.kit.edu/hahn.php). At INT, we conduct fundamental and applied research with a focus on innovation in the fields of nanoscience and nanotechnology. Our scientists collaborate within the institute and with partners around the world across the disciplines of physics, chemistry, and materials science, as well as biology and medicine.
