My research focuses on how the atmosphere, in particular wind forcing, can affect the thermohaline circulation in the North Atlantic. The thermohaline circulation contributes in bringing warm, saline waters northwards and is driven by density differences in the ocean: Warm waters are less dense, but is cooled when transported far north, hence becoming denser. Denser waters sink and flow southwards in the deep ocean. On a monthly/yearly basis large variations in the intensity of this circulation can be seen, also in the deep ocean. Parts of these variations can be caused by the wind, and I aim to find out how. For more info, see here. I am a part of the NFR-project NORTH.

I previously worked with heat transport in the ground, motivated by production of geothermal energy. My focus was on how density currents in the groundwater can affect the heat production. As one creates a temperature difference in the ground by taking up heat energy, this will create density differences in the groundwater, which then can initiate a density driven current: colder groundwater is heavier and flow downwards, while warmer groundwater is less dense and flow upwards. TU wrote an article about this (in Norwegian). I have also looked at how geochemical reactions caused by the temperature change in the subsurface can affect the heat reservoir, and developed better models to describe these changes.
