Main Research Interests

Hydrothermal Ore Deposits, Rare Metals, Fluid Inclusions, Peralkaline Rocks, Geochemistry.

  • My research is devoted mainly to understanding the formation of hydrothermal ore deposits. In particular, I have investigated rare-metal bearing alkaline rocks, orogenic gold deposits, pegmatites, porphyry deposits, and gems. I have worked mostly on sites in North America, West Africa, Morocco, and Madagascar.
  • For the past three years I have been part of the West African Exploration Initiative (WAXI), a research and training program financed by the international mining industry under the coordination by Amira International. The project focuses on the mineral potential of the West African craton, with a particular emphasis on gold mineralization in greenstone belts. 
  • Director of Ore Deposits Team.
  • Head of Microthermometry Lab.
