My research aims to better understand the relationships between microbial biodiversity and ecosystems functions and services. To this end, I combine environmental genomics and bioinformatics to address questions spanning the continuum from basic to applied research. My current activity focuses on reconstructing past marine ecosystems functioning using ancient eukaryotic DNA archived in the sediment record. This work aims to deliver DNA-based reconstructions of the past sea ice cover and carbon sequestration in polar regions.
