Main Research Area

Ocean Modelling, Data Assimilation and Forecasting
Laurent Bertino Staff Picture

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 to 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.

Project leader of the following projects

  1. SeaFINE: Eddy-resolving South China Sea reanalysis
  2. CarboChange: Changes in carbon uptake and emissions by oceans in a changing climate
  3. OC-CCI: The ESA Ocean Colour Climate Change Initiative

Project deputy leader of the following projects

  1. WIFAR: Waves-in-Ice Forecasting for Arctic Operators
  2. eVITA-EnKF: Forecasting non-linear systems using the ensemble Kalman filter and related methods
  3. MERSEA: Marine Environment and Security for the European Area
