About me

I am a postdoctoral fellow at Max Planck Institute for Mathematics in Bonn, Germany.
I spent the 2018-2021 academic years as a research fellow at IBS Center for Geometry and Physics.
I received Ph.D. in 2018 from University of Minnesota under the supervision of Craig Westerland.

My research work focuses on the arithmetic geometry & topology of the moduli of fibrations with applications to:
fibred algebraic surfaces and their moduli stacks, enumerating curves and abelian varieties over global fields.
I am also interested in the theory of smooth 4-manifolds regarding the Lefschetz fibrations.

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