I am a PhD student in climate dynamics at the Geophysical Institute in the University of Bergen and the Bjerknes centre for climate research. I am doing my PhD as a part of the Centre for Climate Dynamics project Dynawarm which focuses on studying the dynamics of past warm climates. More specifically I am looking into the stability of the Arctic ocean sea ice - halocline system, which is believed to have been different in the past warm periods and which is also expected to change in the future. My main interests are the changing freshwater forcing and its effects on the shelf processes and the stratification (especially the formation of the cold halocline) as well as the faith of the warm Atlantic inflow in the changing Arctic. My supervisors are Camille Li together with Lars Henrik Smedsrud and Bjørk Risebrobakken.

I earned my master's and bachelor degrees at the University of Helsinki where I worked with professor Bert Rudels. During my studies I also worked at the marine research department in the Finnish Meteorological Institute. During this time I had the possibility to participate on research cruises as a part of THOR project and I also worked with the first Argo deployments in the Baltic Sea.

I am interested in climate dynamics, especially in different thresholds and abrupt climate changes. In addition to large scale dynamics also small scale phenomena such as mixing and convection are of my interest. Both my master's thesis as well as bachelor's thesis were looking into these questions and now in my PhD I am focusing on the interaction between small and large scale processes.
