The Department of Mineral Sciences is pleased to welcome post-doc fellows Laura Waters and Mattia Pistone to NMNH. Laura completed her PhD degree in Igneous Geochemistry and Experimental Petrology from the University of Michigan, Ann Arbor, MI, working on determining the origins of phenocryst-poor glassy rhyolite-obsidians through detailed petrographic and experimental investigation of phenocrysts within those lavas. While at NMNH, Laura will be conducting experiments with Ben Andrews to constrain and quantify the processes that result in the crystallization of small quantities of phenocrysts in obsidian and allow for the ascent and eruption of lavas that consists of >97% glass.
Mattia Pistone comes to NMNH via ETH-Zurich (Switzerland) where he obtained his PhD and the University of Bristol (United Kingdom) where he finished his first postdoctoral fellowship. Mattia's research interest is on the physical properties of multiphase magmas in the Earth's crust. At the Smithsoniain, Mattia will be working with Elizabeth Cottrell to simulate the evolution of basaltic magmas from the Alaska-Aleutians. The study hopes to experimentally determine how water and oxygen fugacity control magma differentiation in arc-related settings such as that of the Alaska-Aleutians.
