Serin Hong Department of Mathematics University of Arizona, 617 N Santa Rita Ave, Tucson, AZ 85721 E-mail:  serinh at arizona dot edu I am an Assistant Professor of mathematics at the University of Arizona. I am also an organizer for the Arizona Winter School. Before coming to Arizona, I was a Postdoctoral Assistant Professor and a Simons Bridge Postdoctoral Fellow at the University of Michigan. I received my Ph.D. in mathematics at Caltech under the supervision of Elena Mantovan, after receiving my M.S. in electrical engineering and B.S. with honors in mathematics at Stanford University. My research centers around the interplay between number theory, algebraic geometry, and representation theory. I am particularly interested in the Langlands program and p-adic Hodge theory. This academic year, I am serving as a co-organizer (with Pan Yan) for the Algebra and Number Theory Seminar at Arizona. My CV can be found here (updated on Jan 14, 2025).
