Research

Current research topics

My current activity is focused on the design, management and coordination of projects.  These projects contribute to my research activity, which has focused for many years on biogeochemical cycles of carbon and nitrogen in soils that receive organic waste products: carbon storage, quality of organic matter, nitrogen fertilizer value, and losses to water (nitrate) and to the air (ammonia and nitrous oxide).

Current projects

Experimental platform EFELE (2012-2032): long-term trial of the SOERE PRO network. In charge of the platform: management of human resources, financial resources and scientific aspects. Involvement in SOERE PRO working groups (information system development, metrology, etc.).

• Sol-AID (2016-2020): regional project in partnership with the Brittany Chambers of Agriculture; this project aims to develop a web service to estimate soil organic nitrogen mineralization. Project coordinator.
• EPSOLYS (2017-2021): ERDF-Brittany Region project for the design of an embedded system on a trailer for spreading solid organic products (manure, compost, etc.) to allow for real-time assessment of the chemical composition of products applied to the soil. Coordinator of one section of the project.
