My research interests include meteoritics, petrology, and remote sensing (spectroscopy) of asteroids. I use this diverse tool set to understand parent body and solar system processes involved in planetary differentiation. My current projects include assessing the formation of O- and S-rich meteorites and how their evolutionary paths may have differed from more thoroughly-studied planetary materials. By correlating these findings with lab-based spectral measurements of meteorites, we better-inform our interpretations of asteroid spectra, lending insights into the distribution of O- and S-rich environments in the solar system that may be relict from solar system formation or a product of mixing during planetary migration. A more thorough understanding of these factors can strongly influence models of solar system formation and facilitate more efficient space exploration and asteroid resource utilization in the near future.
