Research Interests

I am an early-career research scientist with strong demonstrated expertise in polarimetric radar remote sensing (surface- and satellite-based) of the Arctic and the Antarctic sea ice. Specifically, my research focuses on understanding the critical role of snow cover and its geophysical and thermodynamic properties, impacting sea ice thickness retrievals from radar satellites. My long-term research career goal is to improve our understanding of how snow and its dynamic changes in its geophysical properties impact the accuracy of critical sea ice state variables, estimated from radar remote sensing.  At CEOS, my research (with Prof. Julienne Stroeve) will focus on refining snow and sea ice thickness estimates, acquired from multi-frequency (Ka-, Ku-, X-, C- and L-band) surface-based radar signatures, collected during the 2019-2020 MOSAiC International Arctic Drift Expedition. During my Ph.D., I quantified the impact of snow salinity affecting the accuracy of Arctic sea ice thickness retrievals from radar altimetry. Prior to this Ph.D. research, I was a Research Associate at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (Germany) where my research focused on airborne- and satellite-based radar remote sensing of Antarctic ice shelves.
