Current Research Fields

  • Studying the ice nucleation (IN) mechanism on the molecular level using nonlinear optical spectroscopy to understand the criteria of formation of different types of clouds, which in turn has its influence on climate change. more.
  • Investigating the microphysical and optical properties of ice crystals to help understanding the radiation balance in atmosphere. Studies on Pre-defined clouds are being carried at the AIDA cloud simulation chamber and in situ studies are done with research aircrafts and at high altitude environmental research stations. more
  • Development and application of a novel airborne instrument (PHIPS-HALO) for in situ cloud research. more.


Research Grants

  • Start-Up-Budget (STUB 2012) in 2012 from the competence field Earth and Environment, KIT.

  • DFG project (DFG, AB 604/1-1) in 2014 from the German Research Foundation (DFG).

  • DFG project (DFG, AB 604/1-2) in 2017 from the German Research Foundation (DFG)
