Current Work

My main focus is on the ecology of fungi in soil and plant roots. I'm currently employed on the project "Archaeorhizomycetes - an abundant but entirely unmapped group of soil fungi in Norway", where we aim to investigate the distribution and diversity of fungi belonging to the class Archaeorhizomycetes in Norway. 

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.
