I received my PhD in 2021 from the University of Utah. Since then, I have been a postdoc at UNIST (2021-2022), at UCSD (2022-2025) and at Johns Hopkins (2025-2026).

My research is in arithmetic geometry, a mixture of number theory and algebraic geometry. I am interested in linear algebraic structures arising in the cohomology of algebraic varieties over local and global fields. Typical examples are Galois representations, Hodge structures, isocrystals and structures in p-adic Hodge theory. I am particularly interested in how these vary in families, which has led me to study local and global Shimura varieties.
