CURRENT ACTIVITIES

RESEARCH TOPICS

My research activities focus on the quantitative characterization of the properties and evolution of sediment accumulations, particularly, but not exclusively, in marine settings, and their relationships with regional and local active tectonics.

I use laboratory and field acquisition apparatus (core measurements, well-logging, side-scan sonar, 2D and 3D seismics). I also devise adapted data analysis techniques that use mainly multivariate statistics, image analysis, inversion methods and numerical modelling to characterize the mineralogy, diagenesis, physical properties, dynamics of fluids circulation, strain and stress fields, of the geological formations.

I use these results to investigate the phenomenon of mud volcanism in active marine settings, the geological history and present state of oil basins, the feasibility of CO2 sequestration in saline aquifers.

EXPERTISE

- Acquisition, analysis and interpretation of ocean seafloor imagery (multibeam bathymetry and acoustic reflectivity).

- Acquisition, analysis and integrated interpretation of well-logging data and core measurements.

- Use of Geographic Information Systems (ArcGIS, Microstation) to gather and visualize large projects.

- Elaboration of measurement protocols and analysis schemes, automation of acquisition-analysis protocols, elaboration of numerical models.

- Field mapping and sea-going experience.

Education

- PhD Geology-Geophysics (summa cum laude), University of Montpellier (France)
