Oceanographic knowledge and Research Positions
April 2007 to March 2008:
Post doc
at the LABMON
University of Sao Paulo, Sao Paulo, Brazil
The role of mesoscale and submesoscale activity in the Brazil-Malvinas frontal system and over the South Western Atlantic shelf . Funding is from FAPESP, the Sao Paulo state science fundation. My work is also a contribution to the SACC program (South American Climate Change) whose general goal is to advance the understanding of the coupled effects of global change and climate variability on the oceanic, atmospheric and terrestrial ecosystems of the Western South Atlantic region.
June 2004 to March 2007:  
Associate Researcher
at the
Center for Earth Systems Research,
UCLA, Los Angeles, USA
Submesoscale activity in the California Current System. This part of my research is a component of the CPT-EMILIE (Climate Process Team on Eddy-Mixed Layer IntEractions). It consists in running and analyzing very high resolution CCS solutions (down to 750m).
Co invstigator on "Low frequency variability of the North American West Coast". The focus so far has been on the intense episode El Nino 1997-1998 and the way it impacts the mesoscale activity off the US west coast (downscaling). Upscaling experiments coming soon.
May 2002 to June 2004:  
post-doc
at the
Center for Earth Systems Research,
UCLA, Los Angeles, USA

Development of a Lagrangian model for the Regional Ocean Model System (ROMS) . Applications to advective and dispersive properties of the California Current System (CCS).
Sensitivity of the CCS to atmospheric forcings (Capet et al, 2003, 2006).
Incorporation of interannual variability in ROMS simulations of the U.S. West Coast (USWC) oceanic circulation. This implies to run retrospective Pacific simulations from which boundary conditions for the USWC are derived.

Oct. 1998 nov. 2001:
 
PhD student at the
EPSHOM
, Brest, France
Process studies on the "Generation of oceanic eddies through boundary current destabilization". This involved numerical simulations with a QG model and a isopycnal coordinate primitive equation model (MICOM).   PhD advisors: Drs. X. Carton (Ifremer/LPO) and Y. Morel (EPSHOM/CMO).
Some results are described in Capet et al (2001) and Capet and Carton (2003).
Oct. 1997 June 1998:
Master at the
Laboratoire de Physique des Oceans , Brest, France 
Classes on "Oceanography, Meteorology and Environment".  Three months intern with Dr. X. Carton (Ifremer/LPO) on " Current instability in quasi-geostrophic framework".

Sept. 1994 June 1997:
Student at the 
Ecole Polytechnique, Palaiseau, France
Classes on Fluid Mechanics and Geophysical Fluid Dynamics Three months intern with Drs. C. Thomas (Bordeaux I) and P. Marsaleix (Laboratoire d'Aerologie) dedicated to the "implementation and test simulations of a 3D primitive equation code on the Bay of Biscay area".
