environmental biogeochemist

Currently PhD student, I am studying the influence of organic matter on the trace element dynamics in agroecosystems. This research project aims to improve knowledge on the role of soil and exogenous organic matters on the mobility and bioavailability of trace elements in the soil–plant system in contaminated (natural or anthropogenic) or uncontaminated areas. To achieve this, I use powerful and innovative geochemical tracers, namely stable isotopes and rare earth elements.
