2000-2001 Assistant de recherche, Material Science Department, University of Toronto, Canada. Depuis septembre 2022, directeur du GDR Prométhée dédié aux procédés hydrométallurgiques (orgranisation de journées annuelles et de webinaires). Au cours des dix dernières années, mes activités de recherche ont été consacrées au développement d'approches combinées et génériques visant à la compréhension, à la mise en œuvre et à l'optimisation des processus chimiques et métallurgiques. Les trois piliers de cette approche sont basés sur les calculs d'équilibre thermodynamique, la caractérisation des matériaux et le travail expérimental à l'échelle pilote.
