Hairuo Fu

Welcome! I am Hairuo Fu (付海若), an isotope geochemist, planetary scientist, and paleomagnetist interested in the origins and evolution of planetary bodies. I am currently an Assistant Project Scientist at the University of California, Los Angeles (UCLA), working with Peng Ni in the PTXRt Lab. Beginning in August 2027, I will join the Department of Earth, Environmental, and Planetary Sciences at the University of Tennessee, Knoxville as the Gerald D. Sisk Assistant Professor. I earned my B.S. in Geology from China University of Geosciences (Beijing) in 2016 and my Ph.D. in Isotope Geochemistry from Harvard University in 2024.

I combine high-precision measurements and numerical modeling to understand the behavior of elements and isotopes during high-temperature processes, with the goal of unraveling planetary evolution — including giant-impact events, mantle-crust formation, magma ocean-atmosphere interactions, and metal–silicate differentiation.

Some of my recent research focuses on:

• Constraining the bulk chemical composition of the Moon.
• Integrating geochemical and impact dynamical evidence to test Moon-forming giant-impact models.
• Elucidating the thermal and compositional conditions of the proto-lunar disk using volatile and siderophile elements.
• Investigating the compositional structure of the Moon’s primordial crust and mantle through geodynamic modeling.

Opportunities are open for undergraduate researchers, graduate students, and postdoctoral scholars. Please visit the Opportunities page for details.
