Since 2008 I have been involved in mineral exploration operations and research and development projects on world class mining districts, in Australia (WA, QLD), Canada (QC, SK, and NU), France, and Ireland. My research interests are focused on geological processes associated with ore deposits, at all scales, using a multi-disciplinary approach: from the mineral crystallochemistry to the regional scale geology, and from fundamental studies to their potential application as exploration tools. The common goal of these investigations is the genesis of geological models for ore deposits fully integrated in the geological history. My versatile background in mineral exploration and economic geology with a specialty in ore deposits associated with sedimentary basins (U, Pb-Zn), opens opportunities for collaborations with research institutions and mining companies.  Moreover, my expertise gathered on the extremely diverse uranium geology can be applied to many other commodities for both teaching and research.

My current project funded by the Irish Center for Research in Applied Geosciences (iCRAG) focuses on the geochemical and mineralogical signatures of Pb-Zn mineralization throughout Ireland.

My general interests includes: economic geology, petrography, mineralogy and geochemistry.
