Why do we need so many species?

  For decision making, it is important to understand the long-term consequences of forest loss on both the biodiversity and the human population. Some days “at the office” means more than just a computer and an R script, even to a theoretical ecologist. My doctoral project is carried out in collaboration with research groups from […]

New subsea treating process will allow access to closed gas fields

Extracting oil and gas from subsea production fields is a complicated process. Today it is done from offshore platforms, but the development in the oil and gas industry is towards unmanned production units placed on the seabed. Moreover, subsea operations will allow production in deeper waters, as well as in remote areas with severe weather […]

How cyanobacteria eat iron

  Cyanobacteria (commonly known as blue-green algae) obtain energy from photosynthesis: they use sunlight as energy source to convert CO2 and water to sugar and oxygen. Therefore, they contribute a significant part to global carbon fixation. Just like humans, cyanobacteria require iron to survive. While humans can simply eat e.g. spinach, cyanobacteria need to take […]

CO2 capture with less energy consumption

In order to stall the climate changes, more CO2 emitting industries must install technology for carbon capture and storage. To make this type of technology more available, I work on a way to make CO2 capture technology less energy demandig. Since the start of the industrial revolution, the concentration of CO2 in the atmosphere has […]

How many moose and deer can a modern forest hold?

As a part of my doctoral degree, I study the interaction between large herbivores like moose and deer, and the forests they live in. Moose and deer populations have increased drastically in Norway the last decades resulting in a high browsing pressure that is having an effect on forest tree regeneration. This affects the functioning […]

The connection between space and Earth weather

As a part of my doctoral degree I will learn more about what happens 90 kilometers over our heads. What happens up there today will influence the weather and climate here at Earth in the weeks to come. The atmosphere is really more than just air to breath and rain and snow. It warms us […]
