Biography

Andrew M. Davis is a Professor at the University of Chicago in the Department of the Geophysical Sciences. His research focuses on isotope geochemistry and cosmochemistry, particularly utilizing samples returned by Earth spacecraft to study the early history of the solar system. Notably, he was involved in the groundbreaking discovery that primitive meteorites contain genuine stardust. His work has emphasized the analysis of tiny (less than 10 µm) grains of silicon carbide, graphite, and other refractory minerals that condensed in the atmospheres of dying stars, which provide critical insights into nucleosynthesis and the formation of chemical elements in stars. With over twenty-five years at the University of Chicago, he has developed unique instruments like the CHILI (CHicago Instrument Laser Ionization), which allows for high-sensitivity isotopic and chemical analysis of celestial materials.
