Now
From September 1 of 2023, I joined the Department of Artificial Intelligence at University of Seoul as an assistant professor. The new lab website is now almost ready!
Research Interest
My research interest lies in the theory of computation and applications of automata-related devices. I am especially interested in the problems of computing the edit-distance between formal languages and obtaining the descriptional complexity of regular (tree) languages. I also have been working on reachability problems for automata, matrices, and maps while I was working as a postdoctoral research associate at University of Liverpool with Prof. Igor Potapov from March 2016 to August 2017. From August 2017, I joined AI research center of KETI (Korea Electronics Technology Institute) and started to work on new interesting topics on artificial intelligence based on various deep learning techniques.
Currently, I am an assistant professor of the Department of Artificial Intelligence at University of Seoul in South Korea. As a computer scientist, I love to tackle interesting and challenging theoretical questions especially related to automata and formal language theory. I am also planning to expand my research area into some practical areas such as spatio-temporal data analysis from sports domain and automatic program synthesis, analysis, and repair using deep learning techniques.
