Junjie "JJ" Dong

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 conditions, with particular emphasis on water in the Earth's mantle, phase transitions and melting phenomena, and the 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 received my Ph.D. in Earth and Planetary Sciences from Harvard in 2023, with a secondary field in the History of Science.
