Développement d'outils statistiques afin de quantifier l'expression génétique d'une cellule infectée par un virus ou traitée par une solution thérapeutique.

I developed a method based on truncated pluri-Gaussian random fields to model sedimentary rocks in the subsurface. Gaussian fields are infered based on asymmetric Markovian and non-Markovian transition probabilities between the indicator variable (rock facies). This is done by integrating the Gaussian function based on a truncation rule user-defined. The simulation itself is based on spectral simulation combined with kriging to constrain to local data. These resulted in a geostatistical method able to model complex geological observations like cyclicity and rhythmicity.

Unit testing of algorithms related to kriging on the software SGeMS thanks to Boost C++ Libraries: anisotropic transformations, neighborhood computation, variogram analysis, non parametric statistical distributions. Developed cross-correlated gaussian fields simulator in 3D using turning band algorithm for Pluri-Gaussian Simulations.

This master focuses on modeling subsurface reservoir geometry and resources uncertainties with the research modeling team that develops the geomodeler gOcad. My personal project is to model the effect of faults on channel geometries in an object based simulation context.

The project was to study the possibility of adding fracture modeling in the Leapfrog geomodeling software in order to understand the flow impact for reservoir engineering. The DFN (Discrete Fracture Network) approach was used to model the fractures, and a EPM (Equivalent Porous Media) was used to transfer the fracture properties in a flow grid (TOUGH2). A real case study was done on the Wairakei Geothermal Reservoir, New Zealand. Knowledge acquired : - Geology : Fracture law distributions, fracture permeability - Geostatistics : Kriging, SGS, object-based simulations - Programming : NumPy Library for Python - Geomodeling : Leapfrog software

Flow study in porous medium with the Darcy law. Application on ECLIPSE.

President and project manager of the « Gala du centenaire de l’ENSG ». The event gathered 700 people in Paris taking part in a conference entitled « the part of the engineer in the climate debate». The hosts were engineers and company managers. The same night, we organized a celebration in Paris.
