November 2018: Another successful high school talk is in the books. My favourite comment from one student: "Maybe I should consider becoming a mathematician instead of opening a brewery after graduation..." Later this month, I will be visiting Imre Leader and Benedikt Löwe in Cambridge to talk about recent advances on Hindman-type results for the real line. See my abstract for the Combinatorics Seminar here. Also, more details are being finalized about the European Set Theory Conference and the Advanced Class in Set Theory (aka the next installment of the Young Set Theory Conference) for 2019. The preliminary website is up.

October 2018: I have been organizing some talks at high schools in Budapest and the first one is happening next week. I'll be talking about asymetric cryptography and a nice implementation using graphs. Also, our paper with P. Ellis on cycle reversions was accepted at the European Journal of Combinatorics and the sum-set paper with P. Komjáth, I. Leader, P. A. Russell, S. Shelah and Z. Vidnyánszky will appear in the Proceedings of AMS.

September 2018: We started a Youtube channel for the KGRC where we already posted lectures from our recent conference. We plan to record seminar talks in the future as well. I also have some new notes on Galvin's conjecture based on a recent paper by D. Raghavan and S. Todorcevic.

August 2018: We finalized and submitted the second part of our 'independent transversals' paper with Andres Aranda, Claude Laflamme and Robert Woodrow (see Publications). The Set Theory Today meeting starts in 10 days with 100 people from around the globe. We are ready to both stream the talks live and record them so look out for further announcements.

July 2018: I gave a talk at the Settop conference on ladder system uniformization on trees and uncountable minimal linear orders. Slide are here.

June 2018: I visited the University of Hamburg to talk at the research seminar of the Discrete Math group on dichromatic number problems, and to give an invited lecture at the Undecidability Studierendenkolleg. You can find my slides here on monochromatic sumsets in large direct sums.

May 2018: I gave a talk on Davies-trees at the Séminaire Général de Logique (Paris 7). You can find the slides here.

April 2018: We are organizing an exciting meeting at the KGRC with a long list of great speakers. Click here for more information.

December 2017: I was very happy to receive the Grünwald Géza Prize from the Bolyai Society at the Rényi Institute. The prize is awarded since 1951 to Hungarian mathematicians under 30 for outstanding achievements in pure mathematics research.

I finished my PhD in 2015 at
the Mathematics Department of the University of Toronto. Currently, I am
working at the Kurt Gödel Research Center in Mathematical Logic
(Universität Wien) as a postdoc researcher.

In my research, I study problems that lie on the border of finite and infinite combinatorics, and logic, with a focus on chromatic number and Ramsey-type problems in graph theory and independence results in logic and set theory.

In plain words, I am interested in understanding large, seemingly random and chaotic abstract mathematical objects by looking at the collection of well-behaving substructures with certain properties. How large can these nice substructures be? Can a small number of them cover? My work is motivated by still open classical problems of Erdős and Hajnal from the 1960s, as well as recent research by Komjáth, Thomasse, Thomassen, Shelah and Todorcevic among others. Hopefully you'll find the most important academic informations about me on this website. Feel free to contact me in case you got interested in any of the things I work with.
