I am a glaciologist with a background in physics and geophysics. I am interested in the role of ice in the climate system especially the combination of numerical models with radar and satellite observations. My track record reflects my strong competencies in combining an understanding of physical processes with observations and statistical methods. My work focuses on subglacial processes, reconstructing past accumulation and flow patterns of the Greenland and Antarctic Ice Sheets, the behaviour of ice streams, the properties of polar firn and surface melt, and the water ice deposits on Mars.

See also my ORCID site and my ResearchGate page.

If you are a student looking for projects within the topics of glaciology and/or Mars polar science, please get in touch.


Conducting fieldwork in the polar regions is a privilege. As a senior scientist at the Geological Survey of Denmark and Greenland, I have been able to travel to Greenland at least once a year, and I have experienced amazing landscapes and witnessed the changing Arctic first hand.

Photos from my trips can be seen here but they do not do the landscape justice.
