Academic interests

  • Mixed phase clouds (MPCs): In situ measurements, microphysical properties, spatial distribution of cloud particles, efficiency of the Wegener-Bergeron-Findeisen process, influence of ice nucleating particles and secondary ice on MPC glaciation and lifetime
  • Ice nucleating particles (INPs): field and laboratory measurements of INPs, elucidating the mechanisms responsible for ice formation, physio-chemical properties of INPs, development of ice nucleation parametrizations
  • Holography: cloud particle measurements, phase discrimination and ice crystal habit classification using machine learning
