George Kontogeorgiou

Email: George.Kontogeorgiou@warwick.ac.uk

I am a fourth-year PhD student supervised by Agelos Georgakopoulos.

You can catch me at the Durham Geometry and Topology Seminar (26/1), the Erdos Center Drafting Workshop in Discrete Mathematics and Probability (6-8/2), and the Bristol Geometry and Topology Seminar (14/2).

Academic Background

I obtained my BSc in Mathematics from the University of Athens in 2019. My (unofficial) advisor was Dimitrios M. Thilikos. In 2021 I also obtained an MSc in Pure Mathematics from the University of Athens under the guidance of Christos Athanasiadis. Here is my CV.

Research Interests

I am interested in topological graph theory, group actions, Cayley graphs, and combinatorics in general.

Teaching

During my time in Warwick, I have been a TA for the following classes: Combinatorics, Discrete Mathematics and its Applications I & II, Graph Theory. I have compiled a collection of standard problems aimed at students who are taking their first class in combinatorics.

I have also delivered preparatory lectures for mathematical competitions, both in Athens and in Warwick. I was the deputy leader of the University of Warwick team for IMC 2020 and IMC 2021.
