Prof. Günter M. Ziegler
Discrete Geometry Group, Freie Universität Berlin
Günter M. Ziegler has been President of Freie Universität Berlin since July 2018.
He is an internationally highly respected mathematician who has become known, among other things, for the construction and analysis of complex geometric structures, as well as by the development and the successful use of deeper topological methods for problems stemming from different areas such as for division problems and in optimization.
Günter M. Ziegler was awarded, among others, the Gottfried Wilhelm Leibniz Prize of the German Research Foundation (DFG) and an Advanced Grant of the European Research Council (ERC). He is a member of the Executive Board of the German Mathematical Society and a member of the Executive Board of the International Mathematical Union (IMU). He is a member of the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW), the National Academy of Sciences (Leopoldina), the German National Academy of Science and Engineering (acatech) and a fellow of the American Mathematical Society.

My current work in Discrete Geometry focuses on 4-dimensional polytopes, constructions, enumerative properties (such as f-vectors, see ), their graphs, as well as inscribability questions, cf. . Our topological investigations deal with the existence of equivariant maps, in order to solve problems in Discrete Geometry, such as the existence of hyperplane mass partitions . The Topological Tverberg Problem is another outstanding problem, where the recent counter-examples — see  — raise a lot of new questions.
