Junjie Dong Assistant Professor as of September 2026 Office:  ESS Phone: Email: dong2j@caltech.edu B.Sc., University of Michigan, 2017 Ph.D., Harvard University, 2023 Stanback/3CPE Postdoctoral Fellow, Caltech, 2023–2026 Faculty member at Stony Brook University as of  Fall 2026 Research Webpage

In Fall 2026, I will be joining the faculty at Stony Brook as an Assistant Professor.
I am actively building an interdisciplinary research group. Prospective students and postdoctoral researchers interested in joining are encouraged to get in touch.

My research seeks to understand the large-scale structure and long-term evolution of Earth and other planets by investigating how their constituent materials behave at the atomic level.

We integrate laboratory experiments with computer simulations and use a variety of tools, including multi-anvil presses, diamond anvil cells, molecular dynamics simulations, thermodynamic modeling, and machine learning. These methods allow us to connect the physics and chemistry of planetary materials to geophysical, geochemical, and astronomical observations.

Current areas of interest in my group include:

1. Phase transitions under extreme pressure and temperature conditions
2. The role of water in the evolution and habitability of terrestrial planets
3. The structure and evolution of giant planets and exoplanets
