Nina RAOULT
Post-doc Researcher at LSCE with a Master’s degree in Mathematics (2012, Oxford University) and a PhD in Land Surface Modelling and Data Assimilation (2018, University of Exeter). Currently working on constraining the hydrology and carbon cycles within the ORCHIDEE model using soil moisture satellite measurements.

Natasha MACBEAN
Natasha is an Assistant Professor in the Department of Geography at Indiana University. She was a Research Scientist at LSCE between 2011 and 2016. Her research focuses on understanding carbon-climate interactions and improving future projections using model-data assimilation and synthesis - research she continues to do today. Natasha completed her PhD in Land Surface Modelling and Remote Sensing (2011, University College London). The work at LSCE focused on optimisation and development of the global carbon cycle data assimilation system and the phenology in the ORCHIDEE land surface model, in addition to addressing the challenges of multi-data stream data assimilation using a wide range of satellite and in-situ vegetation, carbon and water flux related observations. She remains a contributor to and collaborator of the data assimilation team at LSCE. |

Pascal MAUGIS
Senior Researcher in hydrological modelling and numerical methods (LSCE). Currently works on constraining hydrological- and thermal-related parameters by in situ and remote sensing measurements. Involved in designing and testing algorithms and tools that automatically generate codes for gradient and adjoint calculation, which are mandatory for usual cost-function minimisation techniques. |

Catherine OTTLE
Senior Research Scientist at LSCE, studying land surface processes for hydrology and vegetation monitoring from local to continental scales. Involved in various developments dedicated to use remote sensing data in land surface models. Currently works on the contribution of land surface products for constraining surface energy and water budgets. |
