Welcome to the PTXRt lab!

As the PTXRt Lab, we explore geochemical processes through the lens of Pressure, Temperature, Composition, Isotopic Ratio, and Time (PTXRt) to understand the formation, evolution, and differentiation of planetary bodies. Our research combines isotopic measurements with high-pressure, high-temperature experiments and kinetic modeling to investigate geological processes on Earth, the Moon, and beyond.

My name is Peng Ni (倪鹏). I am currently an Assistant Professor at the Department of Earth, Planets, and Space Sciences in University of California, Los Angeles. I obtained my Bachelor’s Degree in Geology at Peking University in 2011 and my PhD in Department of Earth and Environmental Sciences at the University of Michigan, Ann Arbor in 2017 with a John Dorr Academic Achievement Award. My PhD thesis focused on studying Cu diffusion in silicate melts and volatile abundances in the lunar mantle. After my PhD, I joined the Geophysical Laboratory (now part of the Earth & Planets Laboratory) of Carnegie Science as a Carnegie Postdoctoral Fellow. During my postdoc, I’ve incorporated non-traditional isotope geochemistry into my research.
