CV

I am a visiting assistant professor at UIUC and my mentors are Chris Leininger and Ilya Kapovich
. Before coming to UIUC, I was a student of Kasra Rafi .

**From Fall 2017 through Fall 2018 I will be a postdoctoral researcher at the
University of Luxembourg
under the direction of Hugo Parlier.
**

On August 2018 I will join the faculty of Department of Mathematics and Statistics at the University of Toledo.

RESEARCH

My research interests are in intersections of low dimensional topology and Geometric Group Theory with emphasis on Out(F_n) and mapping class groups.

More specifically, I am interested in the geometry of Out(F_n) and dynamical properties of the outer automorphisms, subgroup structure of Out(F_n), geometry of the Outer Space and of the simplicial complexes associated with Out(F_n), and developing topological and combinatorial methods for these purposes.

My research papers:

Normal tori in #_n( S^2xS^1),in
Topology and its Applications.vol160,issue8., also in arxiv.
Fully irreducible automorphisms of the free group via Dehn twisting in #_k( S^2xS^1), (To appear in Algebraic and Geometric Topology) updated preprint.

An arc graph distance formula for the flip graph , with Chris Leininger . (To appear in Proceedings of AMS) Preprint in arxiv.

Relative twisting numbers and a distance formula for geometric outer automorphisms of the free group, with Yulan Qing and Kasra Rafi (In preparation)
