Alexis is currently an ESA Living Planet Fellow at University College Dublin (UCD, Dublin, Ireland). Since 2020 he has worked at the Science Foundation Ireland (SFI) Centre in Applied Geosciences (iCRAG) at University College Dublin (Ireland) to study ecohydrological conditions of Irish and British peatlands by using InSAR and SAR observations.
Previously he completed a Master and PhD in Earth Sciences in 2016 and 2019, respectively, at Université Clermont Auvergne (France). His PhD work dealt with the quantification of displacements related to lava flows at Piton de la Fournaise volcano, (La Réunion, France), using Interferometric synthetic-aperture radar (InSAR). He also implemented automatic processing of satellite radar data and developed new algorithms to monitor lava flow emplacements during eruptions.
The “Raised Peatland Ecohydrology Evaluation through Sentinel-1 InSAR data and Machine Learning” (RaiPEAT_InSAR) project will investigate linkages between ecohydrological parameters of raised peatlands and InSAR estimates to classify of ecohydrological dynamics of peatlands. The main objectives are as follows:
