Redouane Lguensat

Dr. Redouane Lguensat is a MOPGA Postdoc on Project Hermès from March 2020.

His research interests are Data assimilation, physically constrained deep learning and methods for parameter estimation. His PhD thesis consisted in the use of analog methods (K-Nearest Neighbor Regression) to develop a new data-driven approach to tackle data assimilation: the Analog Data Assimilation (AnDA). In parallel he also investigated the use of deep learning methods for the segmentation of oceanic eddies from satellite-derived sea related maps and developed EddyNet. In 2018, Redouane Lguensat was a recipient of a postdoctoral grant from CNES (French Space Agency), where he investigated the use of deep neural networks inside ocean numerical codes (e.g. 1-layer quasi geostrophic model).
