Main Research Fields

I am interested in dynamical modelling of galaxies (including the Milky Way), in young stellar groups and open clusters (dynamics, structure, radial velocities, astrometry, runaway stars), in astrometry from space (Hipparcos, Gaia, ...), and in high-time-resolution energy-resolved photon-counting observations in the optical using Superconducting Tunnel Junction (STJ) detectors.


  • Dynamical modelling of galaxies
  • Hyades, OB associations, open clusters, Gould Belt, runaway OB stars
  • Hipparcos, Gaia, space astrometry
  • High-time-resolution energy-resolved photon-counting optical astronomy



Project/mission at ESA

Hipparcos and Gaia.

The Gaia team at ESTEC is happy to support research fellows, young graduate trainees, and interns working on Gaia topics beyond our personal scientific expertise.
