Some major research projects:

  1. LOFAR EoR KSP: I'm PI of a key-project on the Low-Frequency Array that aims to be the first the detect and quantify neutral hydrogen in the first one billion year of the Universe with the goal to study early star and galaxy formation. [PI]
  2. AARTFAAC Cosmic Explorer (ACE): I lead a ~1000hr program with AARTFAAC to set limits on the 21-cm signal of neutral hydrogen from the Cosmic Dawn [PI].
  3. SKA EoR/CD Science Team/SWG: I'm deeply involved in helping to design the next-generation global Square Kilometre Array radio telescope SKA (LOW in particular) for direct tomographic observations of neutral hydrogen only a few hundred million year after the Big Bang, as well as prepare for one of its major key science projects [Founding Chair].
  4. NCLE/Chang'e4: I'm part of the science team of the NCLE instrument on board of the relay satelite for  the Chines Chang'e4 lunar mission. [Science team]
  5. NenuFar: We are setting up a new project to target the 21-cm signal of neutral hydrogen from the Cosmic Dawn with the French NenuFar interferometer, the most sensitive low-frequency array in the world on angular scales of arcminutes to degrees. [Science lead]
  6. Euclid Strong Lensing SWG: I work together with the Euclid Strong-Lensing working group to develop tools to find and model new strong gravitational lens system that ESA's Euclid satellite (2020+) wil discover. [Science Team]
  7. KiDS/VIKING: A new project to find strong gravitational lenses in the VST-KiDS survey, also as test-bed and preparation for Euclid.  [PI]
  8. SHARP: High-resolution follow-up of strong gravitational, using laser guide star adaptive-optics with Keck, HST, VLBI and ALMA. The goals are to constrain e.g. dark-matter substructure in galaxies. [Founding member]
  9. SLACS: The largest strong gravitational lensing survey to date, discovering ~150 lens systems from the SDSS with follow-up using HST, Keck, VLT, etc. The project involved development of state-of-the art lensing and dynamical modelling codes. Goals are the study of galaxy structure and evolution of massive early-type galaxies. [PI]
