About me

 
I am a PostDoc at the Oak Ridge National Laboratory in the Computational Engineering and Energy Sciences group. Formerly, I was a PostDoc at the University of Heidelberg working with Prof. Dr. Guido Kanschat in the Mathematical Methods of Simulation group. Before that I have member of the workgroup Numerical Methods for Partial Differential Equations supervised by Prof. Dr. Gert Lube in the Institute for Numerical and Applied Mathematics at the University of Göttingen.
