Activities

Research

After an education in environmental analytical chemistry and a Ph.D. in soil science focused on the transfer of trace elements in agricultural catchments, I am currently an assistant professor of soil science specialised in soil and water chemistry (e.g. diffuse pollution; biogeochemistry; C, N and P geochemical cycles).

Current research topics

• Dissolved organic carbon sources and pathways in agricultural catchments
• Influence of landscape structure (wetland) in mitigating diffuse pollution
• Climatic and agronomic factors that control dissolved C, N and P fluxes in soils
• Occurrence of veterinary pharmaceuticals in agricultural catchments. Assessment of soil ecosystem services, soil health, and exogenous organic matter

Teaching experience

Assistant professor of soil science, coordination of the Master’s degree TEAM (Transition, Environment, Agrifood Management) and its engineer specialisation. This Master’s degree programme was based on a prospective study that involved many professionals and described the evolution of professions in the environment. Several observations emerged, as follows.

• The environmental dimension is essential in public decision-making
• Climate change and the preservation of resources (e.g. biodiversity, water, soil) require adapting scenarios of development and spatial planning
• Several laws (e.g. energy transition, biodiversity laws, the Water Framework Directive) provide an evolving regulatory framework
• New agricultural models that place the environment at the centre of technical practices are emerging.

This Master’s degree programme has two specific characteristics that are necessary to approach complex environmental issues (natural resources management, food systems):

• A close relation between engineering and social sciences to understand the complexity of processes related to these objects: multi-issues and multi-actors
• An approach to these issues at the systemic level of the territory.
