I am a researcher in geobiology/paleobiology at the Department of Palaeobiology, Swedish Museum of Natural History. My main research interest is the deep biosphere of the igneous crust, both subseafloor and continental. Lately, fungi in such deep environments have been my focus; to understand the diversity, their ecological role and evolution in the deep crust. My research is related to astrobiology and I have investigated deep microbial life in impact craters to understand how such structures could support life at depths on other terrestrial planets. I also explore microbial ecosystems in artificial, subsurface environments like the Stockholm metro system and mines to understand how deep life responds to anthropogenic influence.

I am also an author of fiction and have published one novel and one collection of poems.
