I am a geophysicist / planetary scientist interested in the origin and evolution of terrestrial planets, and my research centers on the question: “How did our planet start to provide an environment that made life possible, and what physical conditions produced such a surface environment?” I believe this is a fundamental question that needs to be answered in the next several decades, yet it requires a collaboration between different disciplines within earth science.
My emphasis has been on the period between the late stage of planetary formation and the beginning of plate tectonics. Despite the shortness of this period compared to the age of Earth, a number of distinct characters of Earth, including core formation, the global-scale melting and re-solidification of the mantle, the generation of the first crust, and the formation of primitive atmosphere and oceans, were produced during this timeframe. I am tackling this evolutionary stage from two different perspectives: planetary formation and magma ocean.
