I am working in the Department of Mathematics at Pennsylvania State University as an S. Chowla Research Assistant Professor (Postdoctoral) with Mihran Papikian. Before that, I received my Ph.D. in Mathematics at National Tsing Hua University in May 2022 under the supervision of Chieh-Yu Chang.
I am interested in various topics of number theory in function fields including:
(1) Arithmetic of Drinfeld modules and t-motives
(2) Transcendence of special values in global function fields
(3) Drinfeld modular forms of arbitrary rank
