Stefan van Waasen received the diploma and doctor's degrees in electrical engineering from Gerhard-Mercator University, Duisburg, Germany, in 1994 and 1999, respectively. The topic of his doctoral thesis was optical receivers up to 60 Gb/s based on traveling wave amplifiers. In 1998, he joined Siemens Semiconductors/Infineon Technologies AG, Düsseldorf, Germany. His responsibility was BiCMOS and CMOS RF system development for highly integrated cordless systems such as DECT and Bluetooth. In 2001, he changed into the IC development of front-end systems for high data rate optical communication systems. From 2004 to 2006, he was with Stockholm Design Center responsible for the short-range analog, mixed-signal, and RF development for SoC CMOS solutions. From 2006 to 2010, he was responsible for the wireless RF system engineering in the area of SoC CMOS products at the headquarters in Munich, Germany, and later in the Design Center Duisburg, Duisburg. Since 2010, he has been the Director of the Central Institute of Engineering, Electronics, and Analytics - Electronic Systems at Forschungszentrum Jülich GmbH, Jülich, Germany. In 2014, he became a Professor for measurement and sensor systems with the Communication Systems Chair, University of Duisburg-Essen. His research interests include complex measurement and detector systems, particularly focusing on electronic systems for quantum computing.
