My research interests are in partial differential equations motivated by physical problems in particular fluid dynamics and material sciences and include:

  • Mixing as a (de)stabilizing mechanism in fluids and inviscid damping.
  • Cascades of resonances and instabilities in fluids and plasmas.
  • Convex integration and microstructures in materials. Rigidity and flexibility.
  • Vortex filaments.
  • Magnetic fluids.
  • Partial dissipation in the Boussinesq equations.
