I currently work as a post-doc at Karlsruhe Institut für Technologie, in the wave phenomena Collaborative Research Center. I am part of the projects A14, AP8, and of the junior research group stability of nonlinear waves.

My research focuses on evolution PDE, and can be briefly summarize with the following keywords:

  • dispersive-diffusive equations, balance laws, reaction-diffusion equations,
  • global well-posedness, asymptotic stability, spectral stability,
  • normal form transform, space-time resonances, amplitude equations, Duhamel formulation, resolvent kernel bounds.
