Welcome to my webpage.

I am an Associate Professor in the Department of Mathematics at POSTECH, South Korea.

My research focuses on the mathematical analysis of partial differential equations (PDEs) arising in kinetic theory and mathematical physics. I study how transport, collisions, self-consistent fields, and boundary conditions shape the dynamics of gases, plasmas, and radiation. The models I work on include the classical and relativistic Boltzmann equations, the Landau equation, the Vlasov–Maxwell system, and radiative transfer equations.

My interests include well-posedness, regularity and regularization, long-time dynamics, and singularity formation. A particular focus of my recent work is on boundary value problems and the construction and nonlinear stability of spatially inhomogeneous steady states. I also investigate the regularizing effects of collisions on singular initial data and the quantitative behavior of dissipative kinetic systems.

Another direction of my research concerns rigorous limits connecting different kinetic models, including quantitative convergence estimates and the effects of changing microscopic interaction laws.
