Research interest

I am interested in measured and asymptotic group theory, in particular spectral theory of graphs and groups, local sampling convergence, graph polynomials, stochastic processes on groups, rank gradient, invariant random subgroups, homology growth, sofic entropy, cellular automata and locally symmetric spaces.

'Invariant random subgroups and their applications', Asymptotic properties of infinite groups, 28 March 2014, Institute Henri Poincaré, Paris: VIDEO and FILE

'Graph convergence, Lück approximation mod p and the entropy of cellular automata', Growth, symbolic dynamics and combinatorics of words in groups, June 2, 2015, ENS, Paris: VIDEO

ERC Consolidator Research Group

Starting in 2015, I am leading the ERC Consolidator Grant "Asymptotic invariants of discrete groups, sparse graphs and locally symmetric spaces" research group. Homepage of the group.

A postdoctoral position is open, starting September 2017 or before. See Postdoctoral position for details.



Open questions

This is a list of questions that I am interested in [PDF]. Many of them belong to other people (when I think I know the source, I name it) and some are purely speculative. It may make sense to contact me before putting a lot of work in one of them as it may have been solved (last update: Nov 2, 2010). Good luck with them.
