BIO

Hi there! 

I am JJ, a 3CPE Postdoctoral Fellow at Caltech (2023–2026). I received my Ph.D. in Earth and Planetary Sciences from Harvard in 2023, with a secondary field in the History of Science, and received  the James Mills Peirce Fellowship. In Fall 2026, I will join the State University of New York at Stony Brook as Assistant Professor.

My research orbits around water on rocky planets and the conditions for habitability, the structure and origin of giant planets, and the behavior of planetary materials under extreme pressure and temperature. I also pursue work in the history and philosophy of science, and am writing on the emergence of American mineral physics in the 1940s, when geophysics met wartime urgency.

I currently live in Pasadena and may be reached at dong2j@caltech.edu.
