Position Continental biogeochemical Si cycle
I am a geochemist whose work focuses on continental weathering fluxes and surface biogeochemical cycles. I am particularly interested in developing proxies to study biogeochemical fluxes in the environment.
General research Interests
"Non-traditional" stable isotopes as proxies for surface geochemical fluxes
Problems related to dust emission from bare soil areas (erosion, air pollution, nearby soil contamination)
Development of new proxies to trace Si fluxes in the rock-soil and soil-plants systems (Si/Ge ratios and Si isotopes).
Quantification of the biogenic Si pools in various soil types.
Use of Si/Ge ratios and Si isotopes for tracing Si cycling in the systems rock-soil, soil-plants etc.
Drought-stress mitigating effect of Si
