  • Cooling of igneous rocks, from the freezing of spatter bombs in the air to the growth of microlites in the glassy matrix of lava flows
    Through experimentally recreating spatter deposits and lava flow morphologies, we can learn how different cooling environments (such as outer space or frozen tundra) affect the thickness of the rind on clasts, or the shape of the quench crystals. I have partnered with the Syracuse Lava Project, the Experimental Volcanology lab as Arizona State University, and the FINESSE group at NASA Ames for my most recent studies, utilizing analog experiments and portable spectrometers to study volcanic landscapes from as close as the Snake River Plane to as far away as Mars.
