Stephanie Suarez (tw: @geologiststephy) is a PhD student specialising in geochemistry and geochronology. Her research interests include chronology of both terrestrial and extraterrestrial materials. She earned her Bachelor of Science in General Geosciences from the University of Texas at Austin in 2017. As an undergraduate researcher, she determined ages of early land biotas to further understand the rate of land colonisation. She earned her Master of Science in Geology from the University of Houston in 2019, where she determined the crystallisation age of Tissint, the fifth witnessed Martian meteorite fall. She is continuing her studies at the University of Houston as a PhD student in Geology and NSF GRFP fellow. Currently, she conducts isotopic and petrologic analyses on Martian meteorites to better understand the nature and timing of magmatism on Mars.
As an undergrad, Stephanie developed improvements to geological dating techniques which lead to the discovery of the age of the oldest land breathing animal.
In our conversation, we talk about being a first-generation college student, make-up, geological dating techniques, and Mars volcanism.
