About

Ren T.C. Marquez, PhD

I am currently a Postdoctoral Fellow for the Buseck Center for Meteorite Studies at the School of Earth and Space Exploration, Arizona State University

Prior to joining ASU, I completed my Ph.D. in Geochemistry at Caltech, where I worked on developing high-precision isotopic tools for studying some of the earliest solids in the Solar System.
