Current research in the Charlet laboratory at ISTerre ( the University of Grenoble
and CNRS) focuses on water geochemistry, investigating the biogeochemical processes in soils, aquifers and organisms, and their influence on mobility, bioavailability,
biotransformation and chemical speciation of trace elements and organics
(e.g. PrP and AMN proteins and antibiotics) in terrestrial aquatic environments
under varying redox and hydrological conditions. We
aim to develop general methods for understanding the
reactivity of nanoparticles present in
natural systems and human body, particularly as a means of predicting biogeochemical
processes that are relevant to environmental quality, sustainability,
nanotoxicity, risk assessment and paleoenvironment reconstruction. Our
group maintains a modern environmental chemistry laboratory specialised
in trace element analysis (particularly Hg, As, Se), surface chemistry,
oxygen-free synthesis, solute and
gas sorption analysis. In several projects we make use of synchrotron
X-ray techniques, such as X-ray absorption fine structure spectroscopy,
neutron scattering, Mössbauer and XPS spectroscopy. Insights provided by
molecular simulations (DFT, MD) confronted to the
spectroscopic/scattering data are critical to a fundamental
understanding of the structure and surface chemistry of natural
(nano)particles
(in particular imogolite nanotubes, clays and carbonates). Current
research projects are mainly funded by CNRS, ANDRA and the European
Union.
The group is represented in numerous French and
international scientific and funding bodies. Outreach activities include
the organisation of Workshops and Conferences.
Laurent Charlet is co-Editor-in-Chief of Journal of Hydrology,
Rovaltain Environmental Toxicology Facility Head of the Scientific
Committe and senior member of the Institut Universitaire de France.
