I am a third-year Ph.D. student in the stable isotope group at UT Austin. My primary research interests are using stable isotope systems, both traditional and non-traditional, to understand high-temperature fluid-rock reactions in igneous systems.
Current Research Projects
Ca, O, and H Stable Isotope Composition of Kaapvaal Mantle Xenoliths
Ca Isotope Composition of the Colorado Plateau Lithospheric Mantle
Source of Cu enrichment in Paraíba tourmaline gemstones
Past Research Projects
Tracking subduction-related metasomatism of the subcontinental lithospheric mantle using Ca-, O-, and H-isotopes
