I am Associate Professor (Førsteamanuensis) at the Institutt for matematiske fag, Norges teknisk-naturvitenskapelige universitet (NTNU) in Trondheim, Norway, since March 2021. I was a postdoctoral researcher and deputy head of the Arbeitsgruppe Numerik partieller Differentialgleichungen, Technische Universität Chemnitz, which I joined in April 2018. Previously I worked within the Image Processing Group, Technische Universität Kaiseslautern, where I finished my habilitation beginning of 2018. Prior to that I was a doctoral researcher and teaching assistant at the Institut für Mathematik, Universität zu Lübeck, working together with my PhD supervisor Jürgen Prestin.
Currently I am working on
nonsmooth optimization on manifolds, especially proximal methods and their application in manifold-valued image processing
optimization methods on manifolds and high-dimensional power manifolds
graph based methods for manifold-valued image and data processing combining both local and nonlocal methods.
anisotropic periodic translation invariant spaces and Fourier based algorithms
