About me

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

My research work focuses on arithmetic of the moduli of fibrations with applications to:
fibered algebraic surfaces and their moduli, enumerating algebraic curves and Abelian varieties over global fields.

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

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

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


I am not teaching for this year.
