Biogeochemical processes of trace metals, isotopic geochemistry
My research is focused on the speciation of contaminants (trace metals) in the environment, and more specifically their interaction with organic and/or natural mineral colloids. I study the controlling factors as the physicochemical conditions (pH, light, redox conditions, complexation, sorption ...) on isotope fractionation of stable non-traditional isotopes. I'm interested in mechanisms elucidation of biogeochemical processes through isotopic fractionation. In this project, we aim to evaluate and optimize a methodology to trace and quantify the spread of Hg from contaminated sediment sites to surrounding sediment and pelagic and benthic biota using Hg stable isotope measurements.
