My research at Irstea was focused on uncertainty and sensitivity analysis for geo-information and GIS-based environmental models.
It included the following topics:
- uncertainty quantification and numerical models exploration in environmental and GIS sciences : uncertainty propagation with Monte Carlo methods, Design of Experiments, statistical methods for sensitivity analysis (Morris, Sobol'...)
- spatial statistics and geostatistics for uncertainty simulation in geo-data
- thematic fields: spatially distributed modelling of natural hazards (flood)
A publication list is available here.
I was involved in two different projects:
QUASIUS (2013-2014): Quality and Uncertainty Assessment for Spatial Indicators of Urban Sprawl

ACBDE-AS (2009-2013): uncertainty and sensitivity analysis for the cost-benefit analysis of flood mitigation plans along the Rhône River. Project funded by the Plan Rhône, a water management body along the Rhône River | info.

Here is an overview of the people I have been involved with in my research activities so far.
Stefano Tarantola & Andrea Saltelli
Joint Research Center, Ispra (ITALY) | info
I went for a 6 weeks visit at the JRC in 2011 to work on variance-based sensitivity analysis for spatial support decision systems.
Members of the GDR MASCOT-NUM research group | more info
Since 2009, I have been attending various meetings and workshops organized by this research group, which is focused on design, modelling and analysis of computer experiments
MEXICO network | more info
This network fosters the use of statistical methods to explore numerical models in biology and environmental sciences. It gathers scientists from various French applied research institutes : INRA, IFREMER, CIRAD, Irstea... They organize each year a spring school on sensitivity analysis for environmental models (this year I gave a lecture on sensitivity analysis for spatially distributed models | pdf).
