Academic interests

  • Mixed-phase clouds (MPC): climate impact, temporal and spatial variability of thermodynamic cloud phase, influence of ice nucleating particles (INPs) and efficiency of glaciation processes on MPC
  • Reflective properties of snow surfaces: surface albedo, bidirectional reflectance distribution function (BRDF), influence of optical-equivalent snow grain size, illumination geometry and surface roughness
  • Remote sensing: visible, near-infrared, terrestrial infrared, radar, lidar (ground-based, airborne, and satellite)
  • Significance of polar regions for Earth’s climate system (e.g. Arctic Amplification) 


2019 – present:   Postdoctoral Fellow, University of Oslo, Norway
2014 – 2018:       Doctoral Research Fellow (PhD), Leipzig University, Germany
