Group Leader / Associate Professor


Håkon Dahle is leading the Dahle Group at the Computational Biological Unit (University of Bergen), and the work-package ‘Energy and Life’ at the K.G. Jebsen Centre for Deep Sea Research (University of Bergen). Dahle has a broad background in microbiolgy and geobiology including isolation and characteriztion of novel species, 16S rRNA amplicon analyses, shotgun metagenomics and metatranscriptomics, phylogenomics, geochemical modelling, thermodynamical calculations, and population dynamic modelling. Study sites have mainly been hydrothermal systems, oil reservoirs, and fish-farms.



Achim Mall is analyzing the diversity of autotrophic microorganisms and their carbon fixation pathways at hydrothermal systems, and how environmental factors shape their distribution.

PhD students


Emily Maria Denny is a PhD student at the Department of Biology (University of Bergen). She is deciphering connections between geochemical settings of natural systems, chemical energy fluxes, and distributions of microbial species and their genes. Her work is primarily focused on microbiomes of deep sea hydrothermal systems.


Linn Merethe Brekke Olsen is a PhD student at the Department of Earth Science (University of Bergen). She is analyzing how mine tailing deposits in Norwegian fjords are affecting the geochemistry and biology of marine sediments.

Master students


Stian Torseth is comparing modelled chemical energy landscapes in hydrothermal systems with microbial community analysis using shotgun metagenomics. He is also expressing and analyzing substrate spectra of selected alcohol dehydrogenases obtained from the metagenomic data.
