I am a postdoctoral researcher hosted by Prof. Atsushi Igarashi at the Computer Software Group, Kyoto University. You may contact me by Sewon@sewonpark.com or by sewon@fos.kuis.kyoto-u.ac.jp.

My research interests include computable analysis, verified exact real-number computation, and formalization of constructive, computable, and classical mathematics in a dependent type theory and its implementation, such as the Coq proof assistant.

This webpage works as my CV when it is printed out. Including boxes like this, unnecessary stuff will disappear in printing.

I started to post some notes in Notes. Take a look!
