Dr. Henry von Wahl

I am a lecturer (akademischer Rat) in the group of Dietmar Gallistl at Friedrich Schiller University Jena.

Research area:

My research focuses on numerical methods for partial differential equations (PDEs) using advanced Finite Element Methods (FEM). My focus is, in particular, on unfitted finite elements (CutFEM), discontinuous Galerkin (DG), and high-order FEM. The applications include fluid dynamics, fluid-structure interactions, problems with moving domains, and atmospheric dynamics.
