Introduction

Irstea UMR TETIS I was working from 2009 to 2015 as a PhD student then as a permanent research fellow at Irstea, UMR TETIS, Montpellier, France. My research was focused on uncertainty and sensitivity analysis for geo-information and GIS-based environmental models.

Research fellow at Irstea (2012-2015)

Irstea 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

Doctoral research (2009-2012)

UMR TETIS I carried out my doctoral research on the sensitivity analysis of a spatially distributed model for flood risk assessment. It involved:

  • assessing the influence of input map uncertainties through geostatistical simulation
  • studying the impact of change of spatial scale on variance-based sensitivity indices
  • exploring model uncertainty in a GIS environment
  • case studies on the Orb river (South-East France) and the Rhône river

I defended my Ph.D. thesis on November, 29th, 2012. The jury was composed of:

  • M. Christian LAVERGNE Professor, Montpellier III University (Research adviser) [home page]
  • M. Hervé MONOD Research director, INRA (Rapporteur)
  • M. Jeroen AERTS Professor, IVM, Netherlands (Rapporteur)>
  • M. Stefano TARANTOLA Chercheur, EC - Joint Research Center (Italie) Examinateur
  • Mme. Bénédicte BUCHER Directrice de recherche, IGN Examinatrice
  • M. André MAS Professeur, Université Montpellier II Examinateur
  • M. Jean-Stéphane BAILLY Enseignant-chercheur, AgroParisTech (research co-adviser)
  • M. Frédéric GRELOT Chercheur, Irstea (research co-adviser)

I went for a 6 weeks visit at the JRC in 2011 to work on variance-based sensitivity analysis for spatial support decision systems.

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

 

mexicoMEXICO 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).
