Research

Currently I am interested in the Zimmer Programme, namely classifying the possible actions that (high rank) lattices can have on manifolds.

I also sporadically look at nocommutative real algebraic geometry (typically for group algebras), and at applications of o-minimality to Diophantine Approximation and Geometric Group Theory.
