معرفی
Valérie Ballu is a CNRS Research Director at the University of La Rochelle, affiliated with the DPL team. Her research focuses on underwater and coastal geodesy, utilizing GNSS, altimetry, and tide gauge data to study crustal movements, subduction zones, and sea-level changes. She contributes to interdisciplinary projects addressing coastal hazards and volcanic activity, particularly in Vanuatu, Mayotte, and the Indian Ocean.
- Research Themes: Vertical and horizontal geodetic positioning, subduction dynamics, and coastal vulnerability.
- Technologies: PAMELi autonomous drone development for coastal exploration.
Her recent work includes monitoring the Mayotte volcanic crisis (2024) and analyzing the Ganges-Brahmaputra-Meghna delta subsidence (2021). She collaborates with geographers, oceanographers, and seismologists, emphasizing interdisciplinary data integration for hazard assessment.
Scientific contributions span seafloor deformation studies (2024), calibration of altimetry missions (2023), and modeling of seafloor geodetic positioning (2021). She holds a HDR (Habilitation à Diriger des Recherches) and actively participates in international conferences like EGU and OSTST.
