Sascha Preu received the diploma degree in 2005, and the Ph.D. degree in physics (summa cum laude) from the Friedrich-Alexander University Erlangen-Nürnberg, Erlangen, Germany, in 2009. From 2004 to 2010, he was with the Max Planck Institute for the Science of Light, Erlangen. From 2010 to 2011 he was with the Materials Department and Physics Department, University of California, Santa Barbara, Santa Barbara, USA. From 2011 to 2014, he worked as the Chair of Applied Physics, University Erlangen-Nürnberg. He is currently a full Professor with the Department of Electrical Engineering and Information Technology, Technical University of Darmstadt, Germany, leading the Terahertz Devices and Systems Laboratory. His research interests include the development of semiconductor-based terahertz sources and detectors, including photomixers, photoconductors and field effect transistor rectifiers as well as terahertz systems constructed thereof. In 2017 he received an ERC starting grant for developing ultra-broadband, photonic terahertz signal analyzers. In 2022 he received an ERC Proof of Concept Grant for further developing photonic Terahertz spectrum analyzers. He also works on applications of terahertz radiation, in particular the characterization of novel terahertz components and materials.
