Research Interests

Our research is focused on understanding how microorganisms interact with their environment and amongst each other in a changing world. We focus on environments that are at the extremes of what we consider habitable and that are also undergoing the most changes due to global warming. Therefore, much of our work is conducted in the Arctic, where we use different models such as terrestrial snowpacks, sea-ice and ice cores to study the limits of life, colonization, microbial activity, adaptation and biogeochemical cycling. Since snow is connected to the atmosphere, our more recent work is related to determining the processes that structure microbial communities in the air and how they are transported across the globe. We are also turning to the past to understand how climate change impacted microbial life by studying ice cores.

Current Projects

MicroLife and In-Space: these international collaborative projects focus on the connection between atmospheric inputs of nutrients and microorganisms and snow microbial communities in the Arctic. Through year-round field campaigns, we are seeking to understand how snowpack communities establish, their activity vs dormancy and how they drive biogeochemical processes in Arctic ecosystems.

Central Antarctic environments – genomic insights into microbial biogeochemisty: A joint project with the Arctic and Antarctic Research Institute in Saint Petersburg. Based on a collaboration initiated through the Franco-Russian LIA on ice cores, we propose to combine our expertise on microbiology and ecology to explore community function and diversity in samples collected from Vostok, Antarctica.
