CV

I am an Assistant Professor at the University of Toledo, department of Mathematics and Statistics.

Previously, I was a postdoc at the University of Luxembourg as a member of the research group of Hugo Parlier.

I am a member of the interdiciplinary ANR/FNR research project SoSANR .

Between 2013-2017 I was a visiting assistant professor at UIUC where my mentors were Chris Leininger and Ilya Kapovich
.I also spent a semester at the MSRI as a postdoc, and there my mentor was
Ursula Hamenstädt.

RESEARCH

My research interests are in intersections of low dimensional topology and geometric group theory
with emphasis on the free group, outer automorphism group Out(F_n) of free group, mapping class groups and right angled Artin groups. I am also interested in computational problems related to optimization on surfaces.

Above is a two copies of an embedded torus in the universal cover of double handlebody (#_n(S^2 x S^1)), and the images of purple intersection disk
under a Dehn twist along this torus. The middle picture is after twisting once, the last picture is the image after
twisting twice.

My research papers:

Normal tori in #_n( S^2xS^1), Topology Appl., 160(8):953--959,2013
, also in arxiv.
Fully irreducible automorphisms of the free group via Dehn twisting in #_k( S^2xS^1), Algebr. Geom. Topol., 17(3): 1375--1405, 2017, updated preprint.
