PUISSANT Jérémy

I am exploring the way microbes react to global changes in mountain soils, particularly the impact of climate change on soil carbon cycling. My research ranges from understanding the precise mechanisms of soil carbon storage in natural ecosystems to a more practical understanding of soil health indicators and function in agricultural ecosystems. The main methods I use are microbial techniques such as enzyme assays, DNA metabarcoding, microbial respiration, and isotope labelling.
