Education
    - Ph.D. from Columbia University (2000) - Dissertation title: Acoustic and Thermal Characterization of Oil Migration, Gas Hydrates formation and Silica Diagenesis (Download PDF [60Mb])
    - Graduate from Ecole Superieure d'Ingenieurs de Marseille (ESIM, Marseille, France) (1991) - Major in Offshore Engineering
    - DEA (~MSc) in Ocean Sciences from the University of Marseille-Aix II (1991)

Interests
  As part of my PhD, I worked on the characterization of the geophysical signature of various processes in marine sediments:
   In situ acoustic properties of calcareous sediments across an OpalA/OpalCT diagenetic front (Download PDF [2Mb])
   Characterization of the in situ elastic properties of Gas Hydrate-bearing marine sediments (Download PDF [8Mb])
   Reservoir Simulation to validate 4-D seismics (Download PDF [30Mb])
   Numerical modeling of the thermal effect of fluid migrations in an active fault zone (Download PDF [11Mb])

  But the real beauty remains in sailing and getting the data at sea... I sailed as Logging Scientist onboard the R/V Joides RESOLUTION on the following cruises of the Ocean Drilling Program (ODP) :
    Leg 148 (1993): Return to Hole 504B, Costa Rica rift.
    Leg 150 (1993): New Jersey Continental Slope and Rise.
    Leg 158 (1994): TAG Hydrothermal Mound, mid-Atlantic ridge.
    Leg 169 (1996): Sedimented Ridges II: Middle Valley and Escanaba trough.
    Leg 185 (1999): Izu-Mariana Margin.
    Leg 201 (2002): Deep Biosphere, Eastern Equatorial Pacific and Peru Margin.
    Leg 204 (2002): Hydrate Ridge, offshore Oregon.
    IODP Expedition 311 (2005): Cascadia Margin Gas Hydrates.

  I also worked as a shore-based scientist on shear sonic logging data from
    Leg 164 (1995): Gas Hydrate Sampling on the Blake Ridge and Carolina Rise

  And spent most of the summer 2006 offshore India drilling for more gas hydrate during NGHP Expedition 1

And if nothing else,
   I run
