Academic interests
My research focuses on glacial hydrology. I use field observations, modeling and satellite remote sensing to gain a better understanding about the dynamics of hydrological systems on glaciers and their connection to glacier dynamics. Part of my work includes multi-year field observations from speleological investigations of englacial and subglacial systems, with a special focus on glacier-permafrost interactions and the influence of changing weather patterns, due to climate change, on the thermal regime of glaciers. The other part of my work is based around the development of new sensor platforms for water flow sensing in hydrological systems of glaciers. This work includes prototype development and testing as well as the development of analysis algorithms to gain novel insights into the dynamics of hydrological systems on glaciers. The geographical focus of my research is Svalbard, where fast changes are currently occurring, but I also have extensive field experience from Greenland and Antarctica.
