Gregor Luetzenburg is a Postdoctoral Researcher at the Geological Survey of Denmark and Greenland (GEUS). His primary project involves developing a database of Holocene marine limits and relative sea levels across Greenland. Gregor is also engaged in mapping the extent of the Greenland Ice Sheet and assessing the impacts of climate change on Greenland's peripheral glaciers. Most recently, he has begun analyzing Holocene relative sea level changes in Southern Greenland using sediment cores from isolation basins. Gregor's background is in coastal geomorphology, with expertise in coastal cliff erosion, landslides, and the effects of climate change on coastal regions.
