Zachary Geballe aims to better understand the Earth’s core by electrical and calorimetric experiments of iron alloys through their melting temperatures at pressures up to 330 GPa. He is also working to improve our understanding of the Earth’s lowermost mantle by measurements of thermal conductivity of the mantle minerals at the pressure and temperature of the lowermost mantle.

    Finally, he translates newly developed methods into physics experiments that discover and characterize high-temperature superconductors, and that deepen our understanding of materials like H2O, H2, and glass-forming silicates such as CaSiO3, all of which exhibit exotic phase transitions that test the limits of cutting-edge physics modeling.
