Junjie "JJ" Dong is a 3CPE Postdoctoral Fellow in the Division of Geological and Planetary Sciences (GPS) at Caltech. His research aims to understand the structure and evolution of planetary interiors through the physics and chemistry of Earth and planet-forming materials. He uses a variety of methods, including high-pressure experiments such as the multi-anvil apparatus and diamond anvil cell experiments, as well as thermodynamic modeling and first-principles quantum mechanical simulations. His current research interests include the early Earth, the deep water cycle, giant planet interiors, and the history of geophysics.

This week we have the second part of Junjie Dong’s insightful blog on modeling the early Earth. Following the discussion (“Modeling the Early Earth: Idealization and its Aims I”) about the major early Earth questions and challenges in modeling early Earth, Junjie now explores the imprtance of modeling as a scientific endeavor. He presents how …[Read More]

Modeling the Early Earth: Idealization and its Aims I

Junjie Dong and edited by Rajani Shrestha July 10, 2024

The question of how we came to be is closely tied with how the Earth became what it now is. What was the early Earth like? How did it evolve to become a habitable world? Given a fragmentary rock record, how can we investigate the early Earth and its evolution? Dr. Junjie Dong from Caltech …[Read More]
