• Research Assistant (Part-time), Department of Mathematics, National University of Singapore, 2013. 8 – 2014. 7.
Research fields:
• Boundary effects and surface wave in hyperbolic systems.
• Asymptotic behaviors on the dynamical systems describing emergent phenomena, which arises from the engineering , physical and biological applications (e.g. Kuramoto model, Winfree model, Cucker-Smale model, etc.).
• Derivability of kinetic equation from particle system with or without noise: uniform mean-field limit and uniform stability of particle system and correspondingasymptotical behavior of measure valued solution.
• Well-posedness of the solutions to kinetic equations and kinetic-fluid coupled system: Vlasov-type equation (e.g. Kinetic Cucker-Smale model, Kinetic Kuramotomodel, Kinetic Winfree model, etc.), Vlasov-Fokker-Planck equation (e.g. Kinetic Cucker-Smale model with diffusion).
