Curriculum Vitae
Dr. Sam Crossley is a planetary petrologist/geochemist/spectroscopist, and the McKay Fellow at the Lunar and Planetary Institute. Dr. Crossley is interested in understanding how the different bulk chemistries of parent bodies inherited from their various reservoirs during early solar system history can affect their subsequent evolutionary pathways (e.g., planetary differentiation). His current work investigates how core formation may have occurred in oxidized, sulfur-rich asteroids in lieu of significant quantities of metal. This investigation utilizes a cross-disciplinary approach that includes the fields of experimental petrology, trace element geochemistry, stable isotope geochemistry, and mineral physics within LPI, NASA Johnson Space Center, and other institutions abroad.
