Associated Project 6 • Stability and instability in fluids and materials

In our research we consider physically motivated problems in partial differential equations, which combine physical effects and interesting mathematical phenomena.
Two particular points of focus here are the role of mixing and resonances in fluids and microstructures in materials.
