I am a postdoctoral researcher with a multidisciplinary background in planetology, photogrammetry, and hydrology. During my Ph.D., I applied remote sensing and hydrodynamic modeling to study surface water processes in the Brazilian Amazon’s floodplains. Part of my work also involved investigating the impacts of climate change on these vulnerable ecosystems using climate models and river discharge projections.

In the context of the DeltAs project, which I joined in May 2025, I will investigate surface water dynamics in Vietnam’s Red River and Mekong deltas using satellite altimetry and Interferometric SAR (InSAR) techniques. My work aims to provide key insights into water levels, flow patterns, and sediment transport, which are crucial for understanding the mechanisms and distribution of arsenic contamination in groundwater and surface water.

I am a postdoctoral researcher with a combined geological and hydrogeological background, and my research is primarily focused on building numerical models of the subsurface and characterizing its heterogeneity. These are particularly useful for better understanding hydrogeological processes such as groundwater flow dynamics, saltwater intrusion or contaminant transport. During my Ph.D., I developed several modeling tools and methods (ArchPy, EROSim) to facilitate the generation of geological models and to better quantify the associated uncertainty of these models based on stochastic methods.

Thanks to this experience with heterogeneity, I hope to bring it into the context of the DeltAs project, where I will develop a detailed geological model of the Mekong Delta that will be used as input to a groundwater model of the same area to capture and predict the evolution of hydrodynamics (groundwater path lines) in this complex system. Ultimately, these, combined with the geological models, will serve as one of the potential keys to understanding the presence or absence of arsenic in groundwater in Vietnam.
