Short CV
Kai Müller studied Physics at TUM. After completing a PhD in Physics at TUM in 2013 he spent two years as a postdoctoral researcher at Stanford University, funded by a Feodor-Lynen fellowship from the Alexander von Humboldt foundation. After returning to Germany he established a junior research group at the Walter Schottky Institut of TUM, funded by the highly-competitive “Quantum Futur” program from the German ministry of education and research (BMBF). Since May 2017, he is one of the twenty members of the “Young Academy” of the Bavarian Academy of Sciences and Humanities. In April 2019 he was appointed as a Rudolf Mößbauer Tenure Track Professor in the Department of Electrical and Computer Engineering of TUM.
Selected Awards

Research Interests
Kai Müller’s research focusses on the photonic quantum engineering of building blocks which are essential for all areas of quantum science and technology, as well as the development of fully-integrated quantum-photonic circuits. This spans the entire range from fundamental quantum optical studies over the development of devices to demonstrator experiments. At its heart lies investigating the light-matter interaction in nanostructures in order to tailor it for emerging applications in quantum communication, quantum simulation, quantum computation, quantum metrology and quantum sensing.
