Research Area: Topology and Groups

My main areas of interest are algebraic topology, group theory and related topics.

Algebraic topology can be described as the study of topological spaces by means of algebraic objects associated to them. This leads to a rich interaction between several areas of mathematics including topology, group theory and geometry, to name a few. Particularly, I am interested in group actions on manifolds, equivariant maps, free rank, index theory, cohomological dimension, and structures on smooth manifolds.

Group theory Group theory is closely related to transformation groups due to abundance of topological spaces admitting non-trivial group actions. The cohomology of groups is a subject which straddles algebra and topology. I am interested in applications of cohomology of groups in the study of automorphisms of finite groups. I am also interested in cohomology of groups as an independent topic.
