Marcel Andree received the B.Sc. degree and M.Sc. degree (passed with honours) in electrical engineering from the University of Wuppertal, Germany,in 2015 and 2017 respectively, where he focussed on the development and optimization of integrated mixed signal circuits. In 2017 he joined the Institute for High Frequency and Communication Technology and is currently working towards the Ph.D. degree. His research interests include terahertz integrated circuit and system design in silicon Technologies. His Research is currently focussing on: THz polarimetric imaging, THz Radiometer design, and THz detector design in  modern nanoscale CMOS and SiGe-HBT technology.
