Laurent Bertino

Research interests
My aim is to improve the stochastic framework for performing data assimilation, other interests include numerical ocean modelling (especially in the hybrid coordinates ocean model HYCOM) and statistics applied to environmental problems. My PhD has borrowed the method of "Gaussian anamorphosis" from the weaponry of geostatistics for further applications of sequential data assimilation into coupled physical-ecosystem models.
2001: PhD in geostatistics from the Ecole des Mines de Paris.
2002: Post-doc at NERSC
2003: Group leader for the Modeling and Data Assimilation group.
2004: Co-director of the Mohn-Sverdrup Center.
2010: Research Director at NERSC.
