Scientist at Institut Agro / UMR SAS

Phone: 02 98 95 99 68

Adress : INRAE UMR SAS, 4 rue Stang Bihan, 2900 Quimper, France

Fields of expertise : Information system, modelling, open science, environmental science

Keywords : Spatial data infrastructure, interoperability, Open Data


Current Research Topics

I work at the interface of environmental sciences, agronomy and information sciences and techniques on research and development of methods and tools in an open science approach.

Through this work, I contribute to the development of an ecosystem of digital services for sharing and making available to the scientific community and beyond, data, models and decision support tools produced by research in environment and agronomy. My first works on this theme were mainly focused on the field of hydroinformatics.

In recent years, I have broadened the spectrum of my research to human and social sciences in an interdisciplinary approach. My approach is to see how the opening of the digital productions of science modifies the work of the researcher both in terms of data acquisition and also in terms of new conceptual possibilities
