• My work in sustainable development focuses on three areas: metrology, expertise, and process implementation. I use tools such as geochemistry, biogeochemistry, mineral processing, computer science, and process engineering. Applications include: recycling and recovery of industrial waste (circular economy); brownfield rehabilitation; polluted sites; biotechnology; precision agriculture; georesources; and built heritage.
