Jörn T. Zimmerling
James Van Loo Post-Doctoral Fellow and Assistant Professor
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.
Inverse problems in acoustics and electrodynamics
Estimation of coefficients of PDEs from remote measurements.
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
