I am working at the National Institute for Mathematical Sciences as researcher since December 2023.
My research interests include scientific computing and mathematical modelling.
I did Master degree in applied mathematics as Kyungpook National University under supervision of Prof. Mingi Lee.
I did Ph.D in applied mathematics at Korea University under supervision of Prof. Seunggyu Lee and Junseok Kim.
