Title of the dissertation: Improving Performance of Mixture of Experts Large Language Models
Supervisor: Assoc. Prof. Marek Cygan (University of Warsaw)

The Workshop on Geometric Topology 2026 (June 7–13, 2026, MIMUW) is an international workshop dedicated to geometric and low-dimensional topology. Speakers include Erkao Bao, Maciej Starostka, Lina Liu, Alexander Doan, Raphael Zentner, Francesco Lin, and Brad Wilson. The focus is on Morse homologies, including equivariant ones, and Floer-type invariants of low-dimensional manifolds. The event program combines formal talks with daily, informal blackboard discussions."
