Research Interest
We investigate the climate’s impact on the polar cryosphere and associated geohazards, ranging from local glacial outburst floods and glacier mass changes to global sea-level rise. To quantify these processes, we employ a multi-method approach combining field measurements such as georadar, UAV-based photogrammetry, LIDAR, webcams, passive seismics, and automatic weather stations.
This framework is anchored in our long-term field site at Freya Glacier in Northeast Greenland. Since 2007, we have maintained this unique dataset—one of only three long-term records on the vast Greenlandic east coast. We utilize these detailed in-situ observations to validate our models, allowing us to upscale findings to a regional level and decipher cryospheric changes in a rapidly warming climate.
