Tröster, Gerhard, Prof.

Gerhard Tröster studied electrical engineering in Darmstadt and Karlsruhe (Germany), earning his doctorate in 1984 at the Technical University of Darmstadt about the design of analog integrated circuits. During the eight years he spent at Telefunken (atmel) Heilbronn, he headed various national and international research projects centered on the key components for ISDN and digital mobile phones. Since 1993 he directs the Electronics Laboratory at the ETH. In 1997 he co-founded the spin-off u-blox ag.
