Junjie "JJ" Dong
3CPE Fellow | Caltech GPS
HI THERE!
My name is JJ. I am a mineral physicist and currently the 3CPE Postdoctoral Fellow at Caltech.
My research focuses on the material properties of planetary interiors under extreme pressure–temperature conditions, with particular interests in phase transitions and melting in minerals, water and redox evolution in terrestrial planets and their impact on habitability, and the composition and structure of giant planets and exoplanets.
I use a variety of research tools, including high-pressure experiments, thermodynamic modeling, first-principles simulations, and machine learning. My research objective is to integrate these techniques in order to connect planetary interiors to geophysical, geochemical, and astronomical observations.
I obtained my Ph.D. in Earth and Planetary Sciences from Harvard in 2023, with a secondary field in the History of Science.

Feb 5, 2025: A news article in the latest issue of the Science Magazine, "New Complexity Emerges in Earth’s ‘Boring’ Middle Region," and a podcast, "How the mantis shrimp builds its powerful club, and mysteries of middle Earth", feature our new paper.
Jan 26, 2025: Our paper on the post-spinel transition has been published on Nature Communications! This project began in the first year of my PhD in 2017, and after seven years, it feels incredibly good to see it come to light. If you're interested in mineral physics, geodynamics, or machine learning, I'd love for you to take a look!
Dec 2, 2024: Our KISS report on the Uranus Orbiter and Probe (UOP) is now on arXiv. This flagship mission could revolutionize our understanding of ice giants and provide foundational knowledge about thousands of similar exoplanets. Let's go to Uranus! 🚀🪐
