Forschung

I am interested in the stability and long-time behaviour of solutions to dispersive PDEs arising in fluid dynamics. Here is a list of my current works.

  1. The effect of stratification on the stability of a rest state in the inviscid Boussinesq system (with Haram Ko, 2025) (accepted for publication in Proc. Am. Math. Soc.) arXiv preprint [arXiv:2508.04514]
  2. Long-time stability of a stably stratified rest state in the inviscid 2D Boussinesq equation (with Klaus Widmayer, 2024) (accepted for publication in Arch. Ration. Mech. Anal.)  arXiv preprint [arXiv:2408.15154]
