My research spans the fields of cosmochemistry, geochemistry, and geochronology. I am interested in the chemical and physical evolution of planetary systems, especially our own solar system. Meteorites are relics from the dawn of the solar system and provide a rich record spanning the entirety of its history. I use computational, chemical, and geochronological methods to reconstruct this history from meteorite chemistry and use this "local" history to better understand the evolution of other planetary systems and their stars. I am also interested in the behavior of glaciers and ice sheets over the Pleistocene (2.5 million years ago to present). I use U-series geochemistry and geochronology to investigate time and process in the (formerly) subglacial environments of the Laurentide and Antarctic ice sheets.
