En résumé

My main areas of interest are numerical simulation and natural hazards. As a research engineer at BRGM, I was mostly involved in research projects dedicated to:

Velocity Structure Inversion
- Velocity structure inversion from horizontal-to-vertical (H/V) spectral ratio of earthquake motions based on the diffuse-field theory for plane waves. Development of a computational code for the inversion of the mechanical properties of 1D soil columns. Sensitivity analysis of the input parameters.

Seismic Wave Propagation
- Development of computational codes with finite difference, finite element, finite volume methods.
- Numerical simulation of real earthquakes. Comparison of observation data with synthetics.
- Modeling of topographic site effects.

Vulnerability Assessment
- Vulnerability assessment of utility networks (e.g. roads, water, electricity). Development of a computational code. Application to crisis management (computation of expected damage from a shake map). Application to the design of seismic risk scenarii (computation of the seismic hazard followed by computation of the damage).
- Vulnerability assessment of buildings. Computation of capacity curves for masonry buildings (software TreMuri). Modeling of the behavior of masonry buildings under seismic loading with a discrete element method (software LMGC90).

CO2 Storage Safety
- Modeling of the hydromechanical behavior of faults during CO2 injection. Development of a computational code and numerical simulations.

Landslides
- Modeling of the evolution of a landslide with a Saint-Venant method.

I have also experience in:
- Answer to project calls from ANR (French National Research Agency).
- Practice of internal quality audit of projects (2 audits per year since 2012).
- Supervision of master students (3 intern students).
