Hei! I am a postdoc in the workgroup Inverse Problems supervised by Prof. Dr. Thorsten Hohage. My current passion is optimal experimental design, that is, the mathematical theory of how to collect experimental data and set up experimental models for the best possible results. I am also interested in inverse problems, partial differential equations, large-scale computing, bifurcation theory and energy disaggregation. Sounds interesting? Then check out my personal home page!
