I am an atmospheric dynamicist with a keen interest in what the atmosphere does with the ocean. My current research focuses on excursions of polar, cold air masses over the comparatively warm waters of the Nordic Seas, so called cold air outbreaks. These bring about a wealth of adverse weather such as polar lows and Arctic fronts that are accompanied by gale force winds and heavy snowfall. Furthermore, they cause enormous losses of heat from the ocean to the atmosphere and they are important drivers behind the formation of cold, dense waters in the Nordic Seas. I am interested in where and why cold air outbreaks form, how they evolve once they feel the ocean, and what imprint they leave behind in the ocean.

Besides that I am interested in everything that flows or rotates on this planet and lives sufficiently close to the poles. In particular, I am / have been working on:

- maintenance of baroclinicity along storm tracks
- energetics of extratropical cyclones
- freshwater fluxes over the Southern Ocean
- role of synoptic weather events for Arctic sea ice variability
