As a research engineer in applied mathematics and spatial remote sensing, I work on the implementation of digital, geostatistical and spatial methods for the management and monitoring of socio-ecosystems. My activities are focused on two complementary fields, the development of observatories with space infrastructures and the analysis of spatial and temporal dynamics of ecosystems subjected to anthropic and climatic pressures. They are part of projects in the South and promote the use of standards and interoperability of systems in an interdisciplinary approach at the interface of scientific issues, operational objectives and technological constraints.
