I am a Post-Doctoral Researcher at the University of Toronto working in the group of Elden Elmanto. Here is my CV.
Rough pronunciation of my name:

Interests:
My interests lie in the fields of Arithmetic Algebraic Geometry and Algebraic K-theory. Currently, I am thinking about motivic cohomology of mixed-characteristic schemes and principal bundles under parahoric group schemes over complete discrete valuation rings.My MR Author ID is 1551361. Here is my arXiv link.
Preprints
-
Gersten's Injectivity for Smooth Algebras over Valuation Rings, submitted.
We prove that the K-groups of the local rings of smooth algebras over valuation rings inject inside the K-groups of their fraction fields.
- Torsors on Smooth Algebras over Valuation Rings, in preparation.
Publications
-
Tilting correspondences of perfectoid rings, J. Ramanujan Math. Soc. 38, No. 1 (2023) 23–32, journal.
We establish Scholze's tilting equivalences of étale cohomology of perfectoid rings algebraically without using tools from almost ring theory or adic spaces.
- Torsors on Smooth Algebras over Valuation Rings, Thesis, accepted
