Research interests:

Claire Zurkowski is a Postdoctoral Researcher in the Equilibrium Physics at Extreme Conditions (EPEC) group at Lawrence Livermore National Laboratory. She received her Ph.D. in Geophysical Sciences from the University of Chicago in 2021 and was a Postdoctoral Fellow at the Earth and Planets Laboratory, Carnegie Institution of Washington before joining EPEC in 2022. Claire specializes in high-pressure-temperature mineralogy, equations of state, and melting. She has explored a range of topics in planetary sciences: including, the light element composition of Earth and planetary cores, chemical interactions at Earth’s core-mantle boundary, the thermodynamic history of meteorites and terrestrial diamond inclusions, and the ultra-high pressure equations of state of planetary building blocks.
