Junjie "JJ" Dong
3CPE Fellow | Caltech GPS
HI THERE!
My name is JJ, and I am a mineral physicist and a 3CPE Postdoctoral Fellow (2023-2026) at Caltech. My research focuses on the material properties of planetary interiors under high-pressure and high-temperature conditions, with particular interests in water and redox evolution in the Earth's interior and their impact on early habitability, the composition and structure of giant planets and exoplanets, and phase transitions and melting in minerals.
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 received my Ph.D. in Earth and Planetary Sciences from Harvard in 2023, with a secondary field in the History of Science.

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! 🚀🪐
