conducts research in the field of low-temperature solid-state physics. He is particularly interested in quantum phenomena in solid-state nanostructures and their application in quantum technology. He received his doctorate from the University of Tübingen in 1987. After postdoc stays at the Electrotechnical Laboratory in Tsukuba and IBM’s T.J. Watson Research Center, he became full professor at the University of Cologne in 1995. In 2000, he became director of the Walther-Meißner-Institute of the Bavarian Academy of Sciences and Humanities, which is combined with a Chair position at TUM. He was the spokesperson of the Collaborative Research Center 631 (2003-2015), served on the executive committee of the cluster of excellence “Nanosystems Initiative Munich” (2006–2019) and is spokesperson of the cluster of excellence “Munich Center for Quantum Science and Technology” (since 2018).
