Background

I am a professional geologist with over 30 years of technical and managerial experience, working for large organisations such as Vale and BHP Billiton, participating and managing complex projects in South America, Australia, and West Africa. Skilled in leading technical services and geological exploration for underground and open pit mines, my career experience includes exploration, mine geology and resource estimations of multiple commodities, geometallurgical studies, mine-to-mill reconciliations, project management and project evaluation.

I have a profound interest in earth sciences and mining. The development and training of junior professionals and geoscientists was one of my passions in the industry. Both interests led me to recently join the academia. My research interests are in the areas of economic geology, exploration geochemistry, geometallurgy and ore body modelling.
