please contact me if you are interested in one of those.
Observer-based data assimilation for time-dependent flows in gas networks (Subproject C05 in SFB-TRR154 funded by German Research Foundation – DFG). This is a joint project with Martin Gugat, FAU Erlangen-Nuremberg.
A posteriori error control for statistical solutions of barotropic Navier-Stokes equations. Project in DFG SPP-2410 jointly with S. Krumscheid (KIT).
Dissipative solutions for the Navier-Stokes-Korteweg system and their numerical treatment. Project in DFG SPP-2410 jointly with Ph. Öffner (JGU Mainz).
