About me

I am a James van Loo Postdoctoral Fellow and Assistant Professor in the Department of Mathematics at the University of Michigan in Ann Arbor, where I work with Liliana Borcea. I received my PhD in 2018 from Delft University of Technology under my thesis advisor Rob F. Remis. During my PhD I spent 5 summers at Schlumberger-Doll Research working on industrial forward and inverse problems.

My research interests lie in the field of numerical methods for partial differential equations, inverse problems and reduced order modeling.

Research interest

Inverse Problems

  • Inverse problems in acoustics and electrodynamics

  • Estimation of coefficients of PDEs from remote measurements.

Forward Problems

  • Efficient numerical solvers for PDEs with variable coefficients and in complex geometries

  • Reduced order modeling

  • Krylov subspace projection methods


  • Fast computation of resonances in unbounded domains

  • Resonances of dispersive media
