Fields of interest:
Algebra, Metric geometry, and Low-dimensional topology. More specifically, my research explores geometric, analytic, combinatorial, and computational aspects of group theory. Examples are (i) the study of asymptotic invariants of groups: a group is considered as a metric space and geometric properties of the space are investigated such as the growth of balls or the isoperimetric inequalities; (ii) the study of C*-algebras associated with groups. Interactions with computer science and topological dynamics as well as probabilistic methods to study "random" group theoretical objects (groups, group elements, subgroups, etc.) are also my research topics.
