Welcome to my personal website! I am an experimental astronomer working at the at the Delft Uniersity of Technology. My current research focuses on developing new types of instruments, which enable us to observe galaxies in the early universe in new ways. I take superconducting electronics and nanotechnology as my main toolbox, because I believe that there are still many unexplored properties of superconductors that can be used for detecting light, in various ways and with very high sensitivity. I currently lead my NWO Vidi program "Dawn of Superconducting Astrophotonics," and I am the co-PI of a NWO-middelgroot program "DESHIMA: On-chip Filterbank Spectrometer for Submillimeter Wave Cosmology." These programs together aim at the development of the on-chip submillimeter-wave spectrometer DESHIMA and obsevations using it. The goal is to probe the cosmic history of star- and galaxy-formation using DESHIMA.
