About me

I am a research fellow in pure mathematics at the University of Melbourne in Victoria, Australia.
Previously, I was a guest at the Max Planck Institute for Mathematics in Bonn, Germany.
Even earlier, a postdoctoral fellow at the IBS Center for Geometry and Physics in Pohang, South Korea.
I received Ph.D. in 2018 from the University of Minnesota under the supervision of Craig Westerland.

My interests lie at the intersection of arithmetic algebraic geometry and algebraic topology.
Particularly, I like to think about the topology of algebraic spaces originating from moduli problems e.g. the moduli space of fibered algebraic surfaces, moduli space of morphisms between certain varieties/stacks.
And their arithmetic implications as enumerating algebraic curves or abelian varieties over global function fields.

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