I am an applied mathematician and assistant professor for computational and mathematical methods for imaging at the University of Hamburg.
My actual research covers large-scale inverse problems in biological and medical applications such as for example fluorescence microscopy, photo acoustic tomography and magnetic particle imaging. More precisely, I am working on variational regularization methods,dynamic inverse problems, Bayesian inversion, and approximation error modelling.
Our paper "Improved image reconstruction in magnetic particle imaging using structural a priori information" is accepted by IJMPI
Our mini-symposium "Mathematical Imaging with Magnetic Nanoparticles" is accepted for the AIP 2017
I have accepted a new position at the University of Hamburg. Start is on 1st of March 2017.

Magnetic Particle Imaging (MPI) is a novel imaging modality for biomedical diagnostics that determines the spatial distribution of magnetic nanoparticles by measuring the non-linear magnetization response of the particles to an applied magnetic field. The advantages of MPI are the high dynamic spatial and temporal resolution and that it does not employ any ionizing radiation.
