Hello! I'm a research fellow in School of Computational Sciences at the Korea Institute for Advanced Study (KIAS), mentored by Prof. Jeong Han Kim.

My research interests lie in algorithmic and structural graph theory.

In an algorithmic sense, I'm interested in NP-hardness, parameterized complexity, and kernelizations of graph problems.

In a structural sense, I'm interested in structures of sparse or dense classes of graphs and width parameters like twin-width, rank-width, and tree-width.

The picture was taken in a beautiful city, Firenze.

Here is my CV (Revised in Jan. 2024).
