Current Work

I currently work 50% as a researcher and 50% as PhD advisor at the Department of Biosciences.


As a researcher, I work with fungi in soil and plant roots. In the project "The plant root microbiome driversity and resilience in a changing climate (DRIVE)," we aim to understand the dynamics of soil- and plant root associated microbes in a changing climate.

PhD advisor

I work as the PhD advisor for the Department of Biosciences (IBV) at the Faculty of Mathematics and Natural Sciences (MatNat) at the University of Oslo (UiO). In this role I help PhD students at the faculty go through the PhD program at IBV, everything from applying to the program to defending their theses. I help with accounting teaching duties for those students who have teaching duties, and am available to give help and guidance to any students who need it about going through the PhD program here.

I also work with international students and maintaining the agreements IBV has with other universities abroad.

Academic interests and background

I am a mycologist with a special interest in root associated fungi and functional versiatility in fungi. I did both my BS (2012) and MSc degree (2014) at the University of Oslo. During my master I looked at the fine-scale spatial structure of the root associated fungi of the ectomycorrhiza-forming plant Bistorta vivipara. After my masters I worked a few months as a research assistant, working with fungal cultures and extracting DNA from soil samples, before I started my PhD in February 2015. I defended my PhD "Functional versatility and diversity in the plant root mycobiome" on the 5th of April 2019.
