Hadal trenches, topographical depressions in the seafloor with depths ranging from 6,000 to 11,000 meters below sea level, act as depocenters of organic matter where microbial life thrives. As a microbial ecologist working with Pr Ronnie N. Glud in the HADAL center, I will study the specificities of microbial life in hadal sediments, both in terms of novel taxonomic diversity and functional potential. I will also investigate the biogeographic processes at play in shaping microbial community structure in these isolated environments presenting a vertical succession of ecological niches.

I am especially interested in archaea, fine-scale genetic variability and microbial lineages involved in the nitrogen cycle. Through the analysis of sequencing data and its integration with biogeochemical parameters, I aim to better understand how benthic hadal microorganisms are involved in element cycling, with communities shaping and being shaped by their environment
