I received both a B.S. and a Ph.D. degree in Geology from the Universidad Nacional de Córdoba, Argentina and a Ph.D. in Oceanography from the Massachusetts Institute of Technology/Woods Hole Oceanographic Institution. After a postdoctoral fellowship and two years as a Storke-Doherty Lecturer in the Department of Earth and Environmental Sciences at Columbia University and as Associate Research Scientist at Lamont-Doherty Earth Observatory, I joined the Department of Geological Sciences at Brown University in 2003.
The focus of my research group is to determine the origin, scale, composition and evolution of the heterogeneity in the Earth's and Moon's mantle using isotope, major, trace and volatile element geochemistry. One of the simplest ways of mapping the heterogeneity in the mantle is using the geochemistry of erupted basalts and mantle peridotites. However, to extract the deep mantle signature from basalts and mantle rocks we must first evaluate the effect that the interaction between melts and the oceanic lithosphere plays in modifying the composition of oceanic island and mid-ocean ridges basalts and massif peridotites. Recycling processes at subduction zones are considered one of the most important means of generating heterogeneity in the mantle. Thus, we have to understand the role that subduction dynamics plays on regulating the distribution of slab, mantle and crustal components between the volcanic arc and the deep mantle. Our research combines field and laboratory work for the collection and analysis of radiogenic isotope (Sr, Nd, Pb, Hf and U-series) and major, trace and volatile contents of basalts, phenochrysts and melt inclusions. Our analytical work utilizes state-of-the-art instruments such as electron and ion microprobe, thermal ionization mass spectrometer, and multi-collector inductively-coupled-plasma mass spectrometer, either using sample solution or in-situ laser ablation.
