About me

I am a postdoc in the group of Prof. Dr. Andreas Frommer at the University of Wuppertal. My interests include numerical linear algebra, (generalized) eigenvalue problems, (generalized) singular value problems, ill-posed problems, iterative methods, subspace methods, and mathematical software.
