  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.
