Together with M. Lewenstein and V. V. Williams I organized a Dagstuhl workshop on Structure and Hardness in P, which was held in November 2016. Feel free to solve any of the 26 Open Problems that came out of this workshop.

With R. Krauthgamer, B. Saha, and V. V. Williams I organized a Bertinoro Workshop on Fine-grained Approximation Algorithms and Complexity, which will be held May 27-31, 2019.

With David Bevan, Miklós Bóna, and István Miklós I am organizing a Dagstuhl workshop on Pattern Avoidance, Statistical Mechanics, and Computational Complexity, to be held March 19-24, 2023.
