David received his B.S. degree in applied physics (with honors) in 2008 at the Fontys University of Technology in Eindhoven for the development of a real-time Fast-Fourier-transform based mm-wave spectrometer. From 2007 till 2010 he worked as a microwave engineer at the Dutch Institute for Fundamental Energy Research Nieuwegein, working on microwave diagnostics for real-time control of electron-cyclotron resonance heating of nuclear fusion plasmas in tokamaks. From 2010 he worked at the Delft University of Technology at the Cosmo Nanoscience group, working on the development and fabrication of terahertz superconducting Niobium-based mixers for ALMA Band 9 and APEX Champ+. Since 2015 he is working in the Terahertz Sensing group (TUD), focusing on reactive sputtering of Niobium-Titanium-Nitride and quality control of thin films and is responsible for fabrication and process development MKID. He authored or co-authored over 30 peer-reviewed papers. His professional experience: reactive magnetron sputtering,wet and dry etching techniques, optical and electron beam lithography, scanning electron microscopy, metrology of thin layers, cryogenic measurements. He was member of the 2017-team who succesfully installed the DESHIMA spectrometer on the ASTE telescope (5000m altitude) in the Atacama desert. First light of this novell and groundbreaking spectrometer was on October 16 2017.
