Hi, my name is Dongryul Kim, and many people also know me as Daniel. I am neither a topologist (Dongryul M. Kim) nor a singer-songwriter (Kim Dong-ryul).
As of December 2025, I’m a fifth-year Ph.D. student at Stanford studying mathematics, advised by Richard Taylor and Pol van Hoften. Before that, I was an undergraduate at Harvard and a student at Seoul Science High School.
My primary interests are in number theory and algebraic geometry, mainly understanding various $p$-adic geometric objects that are used in the Langlands program. Currently I think a lot about Igusa stacks, which roughly parametrize points of $p$-adic Shimura varieties up to some notion of $p$-power quasi-isogeny.
This website is generated and maintained using Zola with a theme cloned from Chirpy. I also host a capsule.
