Research Scientist
Amentum - NASA Johnson Space Center
I am a Research Scientist working at NASA’s Johnson Space Center as a part of the Amentum JETSII contract.
I am a Cosmochemist/Geochemist with a broad interest in the chemical evolution of the Solar System and planets. My primary research focus has been on the following topics.
Origin and evolution of life-essential volatiles in the Solar System and Earth
Mantle and crustal geochemistry
Petrogenesis of oceanic and arc magmas/cumulates
Partitioning of trace elements between minerals and silicate melt

More specifically, I study various meteoritic/terrestrial materials using microanalytical techniques such as secondary ion mass spectrometry (SIMS), to analyze their chemical composition including their volatile contents (C, H, F, Cl, and S) as well as major and trace element concentrations. I have applied these techniques to understand specific research topics such as those listed below.
Chondrule formation and meteorite alteration processes
Volatile contents in Early Earth magmas
CO2 and H2O contents in Earth's mantle and their mantle fluxes
Petrogenesis of mid-ocean ridge basalts, arc magmas, and cumulates
Collaborative study on Andean arc crustal structure combining seismic and geochemical observations
Partitioning of trace elements between amphibole and silicate melt
