Research

My research interest ranges from pure mineralogy to petrology of basic layered intrusions to deep mantle mineralogy and geochemistry. Using various analytical techniques combined with thermodynamic modelling, and based on constrains such as mineral composition and microtextural context, I try to understand petrogenetic links between mantle and crustal processes, with emphasis to ore deposits.
