Forschungsinteressen

I am interested in computational helioseismology which includes in particular

  • the development of forward models: how do waves propagate in the solar interior?
  • the resolution of the inverse problem: knowing the measurements of seismic waves at the solar surface, reconstruct perturbations in the solar interior.
