Overview

My research focuses on extraterrestrial chrome-spinel grains that are dispersed in sediment throughout the Jurassic time period. The unique oxygen isotopes and elemental abundances of chrome-spinels can be used to determine their parent meteorite type, which is used to reconstruct meteorite populations throughout Earth’s history. Throughout this work I have become skilled in the use of the Electron Microprobe and Secondary Ion Mass Spectrometer. I also have experience using FIB and TEM to use the compositions of silicate inclusions in chrome-spinels for parent meteorite classifications.
