About me
I am a Lecturer and a member of the pure mathematics research group at the University of Sydney in Australia.
Previously, I was a research fellow at the University of Melbourne, MPIM Bonn and IBS-CGP Pohang.
I received Ph.D. in 2018 from the University of Minnesota under the supervision of Craig Westerland.
I'm interested in the arithmetic theory of algebraic varieties, moduli spaces with connections to number theory.
Particularly, the geometry of rational points on stacks and counting families of varieties over function fields.
Here are my profiles on Google Scholar, MathSciNet, ZbMATH, arXiv, ORCiD and Curriculum Vitæ.
