Dr. Thomas J. Barrett
SSERVI Postdoctoral Fellow
Dr. Thomas Barrett’s main research focus is isotope geochemistry, particularly volatiles (source(s), amounts) and their evolution in the inner solar system. He received his Ph.D. from The Open University (OU), UK researching the abundance and isotopic composition of hydrogen and chlorine in mineral apatite hosted in basaltic eucrites. During his time as a research fellow at the OU, he explored the effects of impact shock on volatiles in meteorites.
Dr. Barrett uses Secondary Ion Mass Spectrometry (SIMS) to acquire high-resolution and precision data from a variety of samples and a broad suite of instruments to fully characterize their mineralogy and petrology. At LPI Dr. Barrett works with Dr. David Kring to analyze a range of terrestrial and extraterrestrial samples, with a specific focus on lunar samples, with a goal to further constrain our understanding of the different volatile reservoirs active in early solar system history and their evolution.
An ambition of Dr. Barrett’s is to expand his horizons into novel isotope systems and push the boundaries of technique development to meet the unique challenges of working with extraterrestrial material and maximizing the science return for the minimum amount of sample material.
