Oliver Janzer: PhD Thesis Prize in Combinatorics
We are delighted to announce that Dr Oliver Janzer has been awarded the 2022 PhD Thesis Prize in Combinatorics by the British Combinatorial Committee (BCC).
Oliver Janzer has been working as an ETH Zürich Postdoctoral Fellow in the group of Benny Sudakov since 2020. Janzer has received the Prize for his thesis: Results in Extremal Graph Theory, Ramsey Theory and Additive Combinatorics. He did his PhD between 2017 and 2020 at the University of Cambridge under the supervision of Timothy Gowers.
Citation of the British Combinatorial Committee: The thesis contains remarkable and significant contributions in Extremal Combinatorics including a vastly improved bound for the Turán numbers of one subdivisions of complete graphs, the development of a powerful method for counting paths and cycles with a variety of non-degeneracy constraints, and novel results on the Ramsey-type problem of Erdős and Rogers. These results settle well studied open problems of several prominent researchers and their impact is demonstrated by the fact that they already led to a significant amount of subsequent work. A notable example is the brilliant solution by Janzer himself of an old problem of Erdős and Simonovits about the Turán number of cubic bipartite graphs.
