Personal information

Biography

My main research interests lie in the field of continental tectonics and focus on combining structural analysis, geothermobarometry, igneous and metamorphic petrology with high resolution U(-Th)-Pb isotope geochronology to identify and constrain the temporal and spatial scale of processes that serve to modify and/or produce new continental crust. I am particularly interested in the metamorphic, magmatic and tectonic evolution of the Ama Drime Massif, Leo Pargil Dome and Everest Himalaya in southern Tibet and the TransAntarctic Mountains. I am currently developing U-Th-Pb laser ablation capabilities on a Nu Instruments 'AttoM' Single Collector ICP-MS.
