Research vision

My research deals with nature-society interactions. Starting from the needs of local stakeholders, I seek to develop remote sensing tools and state indicators, reflecting the conditions of health, artificialisation and threats to wetlands in diverse landscapes from boreal forests to semi-arid zones and for a long-term monitoring, at different spatial scales. The multispectral and multitemporal data extracted from high-resolution satellite and drone images, combined with rigorous field surveys, allow monitoring these landscapes while limiting or even avoiding the costs of new sampling. My multidisciplinary education combining ecology, geosciences, biogeography and mathematics allows me to best explore environmental analysis for different study scales. I work on the development of robust models, reliable and resistant statically. I implement statistical methods easy to understand and easy to interpreted, for an automated mapping of biophysical parameters and species requirements. I seek to bring tools that help the management of these environments. I therefore work in direct contact with managers in order to develop tools that best meet their needs and constraints. I have developed my skills in dealing with big data of satellite remote sensing through the use of google earth engine directly on the platform and on R via Python, and the use of the sentinel hub. I am now developing routines for series of drone images in diverse landscapes (agricultural and forest environments) combined with fine resolution of satellite images (Planet program for instance) to monitor biophysical parameters and help improving nature based solutions and adaptive management in watersheds. Recently, I have worked on social ecology with the development of protocols based on art to understand the social cognition of wetlands. I also create pedagogical kits for different school levels mixing game, art and sciences to improve the social perception of wetland biodiversity and ecological functions.
