Past projects:

  • 2014-2016: Main contributor to EDF (Electricité de France) project on rainfall extremes. Improvement of their rainfall probabilistic model (operationally applied for extreme flood estimation) using regionalization.
  • 2013-2014: Contribution to INFUZ project (incubation of a startup company in the semiconductor industry). Software development integrating advanced metrology and statistical techniques for "High-Level" data fusion.
  • 2010-2012: Contribution to BATEA project: software development of BATEA (Bayesian Total Error Analysis for hydrological models). This project aimed at providing research support for the Australian Bureau of Meteorology (BoM). I tested BATEA on hundreds of catchments in Australia, solved various parameter estimation issues and participated to the operational integration of BATEA in BoM services, including its deployment and training of BoM employees.
  • 2008-2009: Contribution to “Innovation - Production - Modelling of extreme hydrological event” project for Hydro-Québec. Development of new decision tools for flood frequency analysis. Bayesian modelling of volumes and annual peak discharges, using mixture models and Hidden-Markov chains.
