My research concerns two-phase flow in porous media, focusing on the mathematical modelling on the microscopic pore scale and upscaling to the macroscopic continuum scale as well as solving the resulting nonlinear partial differential equations on both scales. This is relevant for CO2 storage in rock, geothermal energy and oil production. Since the interface between the two phases on pore scale affects their behavior, including their flow through the porous medium on large-scale, understanding the essential processes at the pore scale is fundamental to understand the overall behavior. This work is part of the VisioFlow project.

My research on partial differential equations consists mainly of the following three topics:

  • Analysis: existence and uniqueness of (weak) solutions
  • Upscaling: homogenization, multiple scales, asymptotic expansions, heterogeneous media
  • Numerical methods: convergence, error estimates, discretization (FEM, FVM), linearization schemes
