I use non-traditional stable isotopes to answer outstanding questions in high-temperature petrology. I am fascinated by our ability to resolve tiny differences in isotopic composition between phases and the power of these measurements to inform us about magmatic processes on Earth and other planetary bodies. My initial training was in isotope geochemistry but, soon after gathering my first set of data on natural samples, I realized that robust interpretation of stable isotope data relies on having careful experimental calibrations. A bonus of doing high-temperature experiments is that I now get to make my very own magma! Isotope geochemistry, experimental petrology, and numerical modeling are all integral to my research. Below, you will find links to further information about some of the projects I have been working on:

Geospeedometry using Mg-Fe isotopes in olivine

Origin of main-group pallasites

Spinel-olivine iron isotope oxybarometer

Age of the lunar crust

Synthesis of micro-analytical standards
