David Egger received his Ph.D. in Physics from Graz University of Technology (Austria) in 2013. He pursued his research work as a postdoctoral fellow at the Weizmann Institute of Science (Israel), from 2014-2017. Between 2017 and 2019, he was leading a research group at the University of Regensburg (Germany), supported by the Sofja-Kovalevskaja Award of the Humboldt Foundation. He moved to Technical University of Munich with this award in June 2019, where he was appointed Rudolf Mößbauer Professor.
Selected Awards
2017, Sofja-Kovalevskaja Award of the Humboldt Foundation

Research Interests
The research activities of Prof. Egger focus on atomistic theories of functional materials that drive energy devices such as solar cells. One goal of his research is the discovery of new energy materials which would, for example, allow for a more efficient conversion of sunlight into electricity. To this end, his group develops and applies various theoretical methods for calculating the properties of molecules, solids as well as nanostructured interfaces. These include electronic-structure and molecular-dynamics techniques.
