Marc Peter Westig received the Klaus Liebrecht dissertation price of the Faculty of Mathematics and Natural sciences of the University of Cologne for the year 2014. In his PhD thesis with the title "Quantum limited balanced superconducting 380-520 GHz mixer on a silicon membrane and mesoscopic tunnel devices for terahertz frequencies", he worked on new detector circuits for astronomical applications and on device physics aspects of superconductors out of thermal equilibrium. Key results of his thesis include the experimental proof of the first on-chip superconducting balanced mixer at 500 GHz with quantum limited performance and a new hybrid SIS junction technology, suitable for terahertz frequencies.
