Research Interest
I am a soil microbiologist interested in the roles of soil microorganisms (bacteria, archaea and fungi) in biogeochemical cycles, such as nitrogen and phosphorus cycles, and their spatial and temporal distribution in soils. In particular, I am interested in the environmental drivers that regulate microbial functions and their responses to anthropogenic activity (fertilisation, land use change) and global change. My work focus on arable land (grassland, cropland) in Europe but also in the Southern Hemisphere, and on “pristine” land, such as the Arctic tundra. I have experience of field and lab experiments on bacteria, archaea and fungi, as well as microorganisms involved in the nitrogen and phosphorus cycles. I am familiar with a range of molecular methods (DNA extraction, high throughput sequencing, quantitative-PCR, fingerprinting methods), soil properties analysis, bioinformatics and multivariate statistical analysis (R software). I recently worked on the relationship between the plant and microbial diversity in the Park Grass long-term experiment at Rothamsted Research Institute. I also work extensively on the microorganisms involved in the nitrogen and phosphorus cycles, and how organic and inorganic fertilisation and soil pH alteration affect the balance of the nitrogen and phosphorus cycles in UK grassland and cropland.
