Carnegie Postdoctoral Fellow at Earth & Planets Laboratory

About Me

I am currently a Carnegie Postdoctoral Fellow at the Geophysical Laboratory (now part of the Earth & Planets Laboratory) of Carnegie Institution for Science. I’m an experimental petrologist who seeks to understand the geochemical processes during the formation, differentiation and evolution of Earth and other planets. I utilize a variety of analytical and experimental tools, as well as natural sample studies to solve intriguing questions in these fields.

Before coming to the Geophysical Laboratory, I got my PhD in 2017 from the Department of Earth and Environmental Sciences at the University of Michigan, Ann Arbor with a John Dorr Academic Achievement Award. During my PhD, I studied Cu diffusion in silicate melts to understand Cu-bearing ore deposit formation and volatile isotope fractionation in tektites. I also studied volatile abundances in the lunar mantle by looking at lunar olivine-hosted melt inclusions.

After joining Geophysical Laboratory in 2017, I’ve incorporated non-traditional isotope geochemistry into my research. My current research program aims at understanding the formation and evolution of Earth and other planets by experimentally studying isotope fractionation of Cu and Fe during related processes.
