I am a researcher at the Institute of Mathematics of the Czech Academy of Sciences.

I am interested in discrete mathematical structures, and graphs in particular. Most of my work has been in extremal graph theory. I also work on the recently emerged theory of graph limits, and on the links this theory provides to fields such as real analysis and probability theory.

Project Graph limits and inhomogeneous random graphs.
We have a vivid collaboration with the Extremal graph theory group at the Institute of Computer Science of the Czech Academy of Sciences, and in particular we have a joint seminar.

Teaching

I am TAing exercise classes for Subhash Khot's lecture course Hardness of Approximation: From the PCP Theorem to the 2-to-2 Games Theorem at Prague Schools on Discrete Mathematics 2020, groups Americas and AAAEg1. If you want to send me a solution, please use my gmail account and subject in the format PSSDM exercises America SK, day 2. I am happy to discuss the solutions even after the School ends.

Events that I coorganized

Extremal and Probabilistic Combinatorics Webinar, organized by Diana Piguet, Jan Volec, Liana Yepremyan, and myself. Everyone can join on Mondays using Zoom. While the primary reason for starting this seminar was the COVID-19 pandemic, I fully commune with the sustainability and inclusiveness goals stated on the One World Probability Seminar webpage.
Prague Schools on Discrete Mathematics 2020 was held in the week August 24-28, 2020. Two lecture series was be delivered by Subhash Khot and Shayan Oveis Gharan. A brief report in Czech is here, a more detailed one in English will appear in the December issue of IFORS News.
Zdenek Dvorak and I organized a 2nd edition of the Prague Schools on Discrete Mathematics in July 2018. A short article about the school can be found for example here: [cesky]/[English].
I organized Workshop Graph Limits in Bohemian Switzerland in March 2018.
Zdenek Dvorak and I organized in August 2016 the first edition of what we hope to become a tradition of biennial Prague Schools on Discrete Mathematics. More can be found here. An article about the School appeared in the last issue of the Academic bulletin. [here]
I organised (with Artur Czumaj an Diana Piguet) Workshop on Extremal and Probabilistic Combinatorics in July 2010 in England.
I organised (with Marek Krcal, Bernard Lidicky, and Zuzana Safernova) Spring Schools in Combinatorics 2007 and 2008 in Czech Republic.
