Full Professor at the Geology Department at FCUL. Expert in metallogeny, mineral exploration, and geology of mineral deposits. The main focus of the work carried out has been the understanding of ore-forming processes in different geodynamic settings, aiming at improvements of genetic models, exploration methods, and metallic ores composition. Concerns about the future supply of mineral raw-materials and the need of safeguarding the access to known deposits and promising prospects, were addressed mostly in the past 10 years.
