I study the biogeochemistry of benthic ecosystems, with a particular focus on the Arctic. My background is as varied as the interdisciplinary approaches I use. For my PhD at Penn State University (USA), I studied hydrothermal vents of the Lau back-arc spreading center in the south-west Pacific. I then moved to Ifremer-Brittany (France) for a postdoc in which I used acoustic data to map a deep-sea cold seep off western Africa, and imagery to study the benthic community among turbidity currents of the Congo abyss. My next postdoc was at the Centre for Arctic Gas Hydrate, Environment and Climate (CAGE) at the Arctic University of Norway in Tromsø, where I led my own research on Arctic cold seep ecology.

I am currently a postdoc in the Benthic Ecology group at Nord University. I have two primary research agendas here: sub-Arctic fjord ecology, and carbon and nutrient cycling in the high Arctic. For the first, I make full use of local resources Bodø is, after all, surrounded by beautiful fjords. For the second, I am part of Norway's largest research project, the Nansen Legacy (https://arvenetternansen.com/).

Do animals at the bottom of the ocean know it's dark season?
