Hello! I am Daebeom Choi, a Ph.D. candidate in the Department of Mathematics at the University of Pennsylvania, under the supervision of Angela Gibney and Florian Pop. I received my B.S. degree in Mathematical Science from KAIST. 

I have been supported by the KFAS overseas PhD Scholarship. 

My research interests include arithmetic and algebraic geometry. Here is my CV.

I am one of the organizers of the UPenn Graduate Algebraic Geometry Semimar.
