Awards & Honors

John Eiler Named 2026 Recipient of Geochemical Society's highest honor, V. M. Goldschmidt Award!

"John M. Eiler, Robert P. Sharp Professor of Geology and Geochemistry at Caltech, will receive the V. M. Goldschmidt Award this July. The award named for Victor Moritz Goldschmidt is the society's highest honor, presented annually for major achievements in geochemistry over a career. Prof. Eiler is recognized for research that has transformed the field of stable isotopes, revolutionizing its applications in geochemistry, biochemistry, and environmental sciences. His work on clumped isotopes is of particular significance, with their application resulting in paradigm shifts in, for example, paleoclimate reconstructions, paleoaltimetry, and atmospheric models."
