Department of Mathematics, the Ohio State University

I am currently a Hill assistant professor at the Department of Mathematics, Rutgers University. I received my Ph.D. degree at the Ohio State University in May 2015. My thesis advisor is Roman Holowinsky.

My email address is "zhi.qi [at] rutgers [dot] edu".

My research concentrates on analytic number theory and representation theory, in particular, automorphic forms, L-functions and the theory of high-rank Bessel functions.
