Research: Topology, geometry, geometric group theory, dynamics...

I work on actions of infinite groups on manifolds. Some of my work involves the relationship between the algebraic and topological structure of diffeomorphism and homeomorphism groups, the large-scale geometry of such groups (e.g. subgroup distortion) and dynamical consequences of algebraic properties. I am also motivated by the study of geometric examples, actions "at infinity" and their rigidity properties.

In simple English: I work with abstract spaces and try to understand their shape and the structure of their symmetries or how flexible or rigid they are. Sometimes the spaces are themselves collections of mathematical objects (for example, you could think about the space of all 1-variable functions, or the space of all solutions to a problem or...). This gives us new tools to understand these objects.

Some projects I am involved in:
Cornell Topology Festival
Cornell math DRP
• The Directed Reading Program network, an NSF-funded project to support undergraduate-graduate independent study/reading programs in mathematics.
Topology Students Workshop
