I am a Zorn Postdoctoral Fellow at Department of Mathematics, Indiana University Bloomington. My postdoc mentor is Mike Mandell. You can contact me at nz7 at iu dot edu.
In Fall 2026, I am visiting the Max Planck Institute for Mathematics in Bonn, Germany. In 2020 -- 2023, I was a Hans Rademacher Instructor of Mathematics at University of Pennsylvania, working with Mona Merling. I received my Ph.D. from University of Illinois at Urbana-Champaign in May, 2020, advised by Matthew Ando.
My main research interest is algebraic topology and its relations with algebraic geometry and number theory. For more details, please check my publications and preprints below and my talks and notes page. I am on the tenure-track job market in Fall 2026.
