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 Center for Geometry and Physics, IBS.

My research work focuses on the arithmetic of the moduli stacks of fibered algebraic surfaces.

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

### Teaching

I am not teaching for this year.
