Constance lefebvre

PhD Student
Université libre de bruxelles (ULB)

I am a PhD student at the Université libre de Bruxelles (ULB). I started my scientific journey as a geology student at ULB, where I completed both a bachelor and a master’s degree. While all my friends were fascinated by rocks and volcanoes, I fell in love with the polar regions. I decided to devote my master’s thesis to modelling methane transport in Arctic sediments. My current research as a PhD student focuses on the decomposition of organic matter in thawing Arctic subsea permafrost, microbial controls over the production of methane and CO2, and the fate of these (dissolved) gases in the sediment column. It involves a lot of code and playing around with some cool mud. Understanding how microbes react to the evolution of their habitat under climate change will help us predict carbon fluxes from the Arctic seafloor to the ocean in coming centuries. I love talking about science and the Arctic in particular. I joined APECS to share my love for this amazing region.
