Baptiste Journaux
Assistant Professor at University of Washington
Seattle, Washington, United States
Summary
👤
Senior🎓
Top SchoolBaptiste Journaux is an assistant professor and planetary scientist with eight years of experience probing the thermodynamics of water and ices under extreme pressures and temperatures to constrain habitability in icy moons and water-world exoplanets. He leads development of SeaFreeze, an open-source code delivering high-precision thermodynamic models for water and high-pressure ices, and couples that modeling with hands-on Diamond Anvil Cell experiments, Raman spectroscopy, and large-facility neutron and X-ray techniques. His work blends experimental innovation—designing cryo/heating systems for high-pressure cells—with theoretical thermodynamic modeling to map phase diagrams, equations of state, and partitioning relevant to planetary interiors. Based in Seattle at the University of Washington, he brings a rare combination of lab engineering, synchrotron/neutron experience, and planetary field knowledge, having traced this line from a PhD on salt–water phase relations to NASA postdoctoral work.
