The research concentrates on the properties of the interstellar medium and the process of star formation, both in the Milky Way and other galaxies. 

The main topics include:

  • Physical and chemical properties of interstellar molecular clouds and the initial conditions for star formation by means of radio spectroscopy
  • Properties and composition of interstellar dust grains by observing continuum emission from dust
  • Measurement and modelling of the Extragalacic Background Light (EBL) in the optical and infrared
  • Numerical radiative transfer modelling of spectral lines and dust continuum emission in interstellar clouds
  • Numerical magnetohydrodynamical modelling of the physical properties of the molecular clouds
