Research Interests

Se -Te elemental and Se isotope signatures in mantle xenoliths from active subduction zones (Patagonia) to identify mantle sources and crust-mantle transport mechanisms for ore metal enrichment.

Application of the non-traditional stable Se isotope system to high-temperature rocks from the Archean to modern times to characterize the chalcophile and volatile budget of the Earth’s mantle.

Petrology and geochemistry of ultramafic mantle rocks (peridotites and pyroxenites) and associated crustal rocks to understand the origin of elemental and Sr-Nd-Pb-Hf radiogenic isotopic heterogeneities of the lithospheric mantle.

Isotope mixing models to identify potential end-members (terrestrial and extra-terrestrial sources) in providing the isotope signatures of mantle material.
