I offer numerous mapping services involving the research, analysis, integration, and modeling of geospatial and topographic data.

I initiated the deployment of a data infrastructure to centralize technical data (vineyard & oenology data from the AOC Champagne), supported numerous missions involving the georeferencing of technical data, and enabled teams to improve their GIS skills.

My doctoral thesis in geomorphology aimed to explore the following topic: "Instability of the slopes of the Champagne vineyards: analysis of forcings and hazard modeling."

During these three years of academic research, I consolidated my skills in geospatial data modeling, notably by creating a multi-parameter model to assess the vulnerability of vineyard slopes to slope instability based on several criteria (topographical, biomass indicators, hydrological indices).

I have:

- prepared numerous geophysical surveys (electrical resistivity), which involved analyzing historical aerial photographs and GIS analysis of slopes before deploying power lines (l = 400-600 m) in the field,

- created numerous 2D and 3D lidar models,

- created GIS maps of landslides,

- created a satellite database (NDVI, MSI, EVI, NDWI, RGB) to model vineyard biomass and water stress,

- participated in the processing of results from several drone photogrammetry campaigns that led to the modeling of an unstable slope (resolution achieved: 0.6 cm/pixel),

- organized and participated in hydrological survey campaigns,

- created and published academic articles in French,

- participated in several national and international geography conferences.
