Susan Kieffer

    My research interests are broadly described as geological fluid dynamics, and they include field, theory, and experimental aspects.

    Planetary and Terrestrial Volcanoes and Geysers

    Study volcanoes and geysers on or near the surface of the Earth and other planets and satellites, including Mars, Io (a satellite of Jupiter), Enceldaus (a satellite of Saturn), and Triton (a satellite of Neptune).

    Shock Waves and Hydraulic Jumps in Geological Flows

    Examine the effect of shock waves in volcanic eruptions and meteorite impacts and that of hydraulic jumps in river flows. Apply the shallow water/compressible flow analogy to the study of volcanic eruptions.


    Develop phase diagrams and equations of state for substances at the extreme conditions found in geological flows.
