I am an applied mathematician and assistant professor for computational and mathematical methods for imaging at the University of Hamburg. Therefore, I am member of Center of Optimization and Approximation.
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 project "Multi-messenger x-ray science - Solving inverse problems of x-ray crystallography with constraints by x-ray emission spectra" has been accepted for funding from the DESY Strategy Fond
I will give a talk at the EUCO in Trier in September 2018.
Welcome to Christiane Schmidt in our research group. She starts on 1st December her PhD project.
Our mini-symposium "Mathematical and Computational Aspects in Magnetic Particle Imaging" is accepted for the SIAM Imaging.

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.

University of Eastern FinlandI will give the bachelor course on optimization during sommer semester 2018. The course will cover a introduction to optimization techniques in finite dimensions including theory and practical implementations.
I organise together with Stefan Heitmann the Lothar Collatz Seminar
Inverse Probleme nennt man in den Naturwissenschaften solche Fragestellungen, in denen man von beobachtbaren Wirkungen auf deren Ursachen schließen möchte. Bildgebende medizinische Verfahren sind ein inzwischen alltägliches Beispiel, die Wettervorher-sage ein anderes. In dieser Vortragsreihe beleuchten wir nur scheinbar verschiedene Anwendungen und deren gemeinsames mathematisches Rückgrat.
