Areas of Specialization

Research

My research presently focuses on three primary themes: • Material cycling at convergent margins; sediment and altered oceanic crust inputs vs. arc volcanic outputs • Magmatic volatile budgets and the effects of H2O on mantle melting • Solid earth volatile cycles and the long-term evolution of the oxidation state of the earth's crust and interior. A new, state-of-the-art laser-ablation ICP-MS lab has been installed at GSO, and is actively used for the analysis of trace elements and isotope ratios in silicate melt inclusions, minerals, and submarine glasses. I also use state-of-the-art synchrotron facilities at NSLS and APS to develop and employ the XANES technique for analysis of Fe3+/∑Fe ratios in glasses and melt inclusions.

Teaching

I currently teach the following courses: •OCG 110: The Ocean Planet (w/ Kincaid); Next offered Fall 2013 •OCG 525: The Chemistry of the Earth (w/ Spivack); Next offered Fall 2013 •OCG 628: Petrology of the Oceanic Crust; Next offered Spring 2015 •OCG 643: Subduction Zones (w/ Kincaid); Next offered Spring 2015 •OCG 645: High-Temperature Geochemistry; Next offered Spring 2014
