*About Me*

I am a second year L.E. Dickson instructor in the Department of Mathematics at the University of Chicago. I graduated from University of Maryland, College Park in 2013 under the supervision of Prof. Dmitry Dolgopyat.

My detailed CV can be found here.

*Research Interests*

Currently I am interested in the following fields: Hamiltonian dynamics, hyperbolic dynamics, symplectic topology.

*Education and Experiences*

During the past years, I visited the following places and was influenced by a number of mathematicians from various fields.
