Graduate Students

Sarah Brooker , Ph.D., expected 2026 (Supervisor)
I am a second-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.

Fernando Rey , Ph.D., expected 2025 (Committee Member)
My research focus is to link the stratigraphic record with tectonic processes using geochronology and geochemical signatures. I am currently working on projects in southern Patagonia (Late Jurassic-Early Cretaceous Rocas Verdes Back-arc basin) and Japan (Neogene opening of the Sea of Japan).I am also interested in the dispersal of sediments in shallow marine environments. I have 8 years of experience...

George H Segee-Wright , Ph.D., expected 2024 (Co-supervisor)
I am a mantle geochemist with a focus on volatile element cycling between Earth's surface and mantle. I am interested in combining radiogenic and stable isotope measurements to better constrain lithospheric recycling into the mantle. My current research focuses on using halogen abundances and chlorine isotopes to trace subducted volatile elements into the sub-continental lithospheric mantle and the convecting mantle.
