I am a Chapman fellow in Mathematics in the Applied Mathematics and Mathematical Physics section. My research lies in the fields of Analysis of Partial Differential Equations and Probability.

I am especially interested in:

  • Stochastic homogenization for elliptic operators
  • Random walks in random environments and interacting particles systems
  • Fluid flows in porous media
  • Magnetic Schrödinger operators

Before joining Imperial College, I was an Hausdorff postdoc at the University of Bonn in the group of J.J. L. Velázquez. I received my PhD at the Max Planck Institute for Mathematics in the Sciences of Leipzig, under the supervision of F. Otto.
