Hi! I am a researcher at IGN, the French National Geographical Institute, in the machine learning department STRUDEL. The focus of my research is to develop new optimization and learning methods to exploit the structure of remote sensing data (spectral, spatial, temporal, multi-modal) for improved precision and speed.
During my PhD at INRIA I studied learning and optimization structured by large graphs (total variation, graphical models, etc). I now work on machine learning and computer vision applied on remote sensing challenges such as 3D point clouds analysis and satellite superspectral time-series. I have also developed an interest for structured deep models, such as graph convolutions and attention-based encoders.
I am the main investigator of the ReADy3D ANR project on Real-time Analtsis of Dynamic 3D data.
See my academic_CV for more details (updated in April 2021).
NEW: Our CVPR Workshop EarthVision have been accepted. Great line-up of speakers, contests, and as always a must for meeting remote-sensing researchers intersted in the latest advances in computer vision. stay tuned for more info!
NEW: Our paper presenting Torch-points3D havs been accepted as an oral at 3DV 2020. Congrats to the awesome dev team for their impressive work.
