Dongnam Ko is a Ph. D. Currently he holds a Postdoctoral position at the ERC Advanced Grant project DyCon under the supervision of Prof. Enrique Zuazua (Universidad Autónoma de Madrid and DeustoTech). In the past, he collaborated within the HYKE research group in the Seoul National University.
My primary field of expertise is the analysis of hyperbolic and kinetic Partial Differential Equations, especially on the long-time behavior of the systems and limit models related to the characteristic curves. From both the theoretical and numerical points of view, I studied stochastic and control theories on the collective dynamics. My research interestes covers:
- Long-time behavior of coupled particle networks with and without noise.
- Control problems on nonlinear nonlocal mean-field models.
- The large population limit from the finite-dimensional system to the kinetic equations.

On the emergence of local flocking phenomena in Cucker-Smale
Advisor: Prof. Seung-Yeal Ha – Seoul National University, South Korea
Description: In this thesis, we study the local flocking phenomena in Cucker-Smale model from the particle description to the hydrodynamic one. We focus on constructing proper Lyapunov functions and long-time behavior under a sufficient condition of parameters.
