Research in brief

On one side, extremal and probabilistic questions about graphs and hypergraphs: colourings, Ramsey numbers, embeddings, sparse regularity. On the other, what learning algorithms (best-response dynamics, no-regret learners, reinforcement learning) actually do when they play games against each other. The research page has papers, talks and open projects; the teaching page collects course material.
