Dr. James Day : Professor

Dr. James Day



I am a geologist and geochemist focusing on the research of volcanism and what the mineralogy and composition of rocks can tell about how the planets formed and evolved to their present-day states. I study asteroids and products formed in the mantle of Mars, the Earth, and the Moon. I also study terrestrial basaltic volcanism to further understand crust formation processes and the role of volcanism on Earth system cycles.
