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 a LunaSCOPE Postdoctoral Fellow at Brown University, working with James Dottin in the SLAB lab. 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.
