Kajetan received his B.Sc and M.Sc in physics from the Wroclaw Technical University for his work on time resolved spectroscopy of nanostructures. Recently he is a PhD student in the quantum transport research group of Prof. Dr. Laurens W. Molenkamp in Wuerzburg dealing with novel topological phases of matter. Kajetan’s primary research area covers magnetic topological insulators exhibiting the quantum anomalous Hall effect.
