Soumya Ray (Ph.D. Candidate, School of Earth and Space Exploration) M.Sc. University of Delhi (2012) – Soumya is measuring the Fe isotope fractionation in achondrite meteorites, as well as analyzing their Si isotope composition, in the ultra clean Isotope Cosmochemistry and Geochronology Laboratory. Her Fe isotope work on aubrites, in particular, has provided new insight into the formation of metal nodules in these unique meteorites.
