My CV

My research lies at the intersection of dynamical systems, topology and geometry, with applications in number theory, percolation and other areas. My recent projects include applications of Cantor dynamics in the study of properties of the profinite Galois groups, and the properties of flows on flat surfaces of infinite genus. I am also interested in group-theoretical and geometric aspects of percolation on Cayley graphs of non-abelian groups.
