About me

I received Ph.D. in 2018 under the direction of Craig Westerland at University of Minnesota.

Prior to finishing my dissertation, I was fortunate to cover mathematics in various étale sites;  Williams College,  Penn State - MASS Program,  Independent University of Moscow - Math in Moscow, and Brown University.

I'm currently a postdoctoral research fellow at IBS Center for Geometry and Physics.

I am familiar with Geometry & Topology of 4-Manifolds;  Arithmetic of Moduli Stacks of Algebraic Surfaces.

Here are my profiles on Google Scholar, MathSciNet, ZbMATH, and arXiv.


I am not teaching for this year.
