Professor, University of Bayruth
(Post Doctoral Research Associate, ASU School of Earth & Space Exploration, 2007-2011)
Dr. Bouvier is interested in unraveling the chronology of planetary processes that took place during the first few million years of Solar System history such as the formation of the first condensates in the solar nebula, and the accretion and evolution of planetesimals.
 
 
Staff Scientist, Lawrence Livermore National Laboratory
(Ph.D. studies, ASU School of Earth & Space Exploration, 2007-2010)
Dr. Brennecka studies uranium isotope variations in Solar System materials, with a primary focus on how those variations affect early Solar System chronometers, as well as apparent nucleosynthetic anomalies in CAIs (calcium- and aluminum-rich inclusions).
 
 
Assistant Professor, Department of Geosciences, University of Alabama
(Post Doctoral Research Associate, ASU School of Earth & Space Exploration, 2014-2016)
Dr. Cartwright studies the formation of planetary regoliths and fluid processes in meteorites, as well as achondrite meteorites to understand the formation and evolution of their parent bodies and the Solar System as a whole.
 
 
51 Pegasi b Postdoctoral Fellow, University of California at Los Angeles
(Ph.D. studies, ASU School of Earth & Space Exploration, 2013-2020)
Dr. Dunham analyzes the beryllium and boron isotopes of refractory materials from primitive meteorites in order to better constrain the processes that occurred in the extreme environment predating planetary formation in the early Solar System.
 
 
 
Post Doctoral Research Associate, Lunar and Planetary Institute (USRA) / NASA Johnson Space Center
(Ph.D. studies, ASU School of Earth & Space Exploration, 2013-2020)
Dr. Dunlap uses short-lived radionuclides such as Al/Mg and Mn/Cr to investigate the timing of melting and differentiation on early forming asteroids and planetesimals to better comprehend the formational timeline of the rocky bodies in our Solar System.
 
 
Geologist, Regulatory Compliance Officer and Strategist – Native Restoration Services, Inc.
(NASA Space Grant Undergraduate Fellow, ASU School of Earth & Space Exploration, 2013-2016)
Elizabeth Dybal's work involves restoration of native prairies, woodlands, and wetlands in northeastern Illinois.
 
 
 
Associate Professor, Department of Geological Sciences, University of Cape Town
(Associate Research Scientist, ASU School of Earth & Space Exploration, 2006-2012)
Dr. Janney's research involves the application of elemental, radiogenic isotope and "non-traditional" stable isotope techniques to understand the geochemical evolution of the Earth’s mantle and crust.
 
 
Post Doctoral Research Associate, Lunar and Planetary Institute (USRA) / NASA Johnson Space Center
(Ph.D. studies, ASU School of Earth & Space Exploration, 2011-2017)
Dr. Mane studies the hydrogen isotope composition of martian meteorites to acquire insight into martian water reservoirs.  She also analyzes refractory inclusions found in primitive meteorites, considered to be the first solids to condense in our Solar System.
 
 
Post Doctoral Fellow, CRESST II/CUA/NASA Goddard Space Flight Center
(Ph.D. studies, ASU School of Earth & Space Exploration, 2011-2017)
Dr. Mercer performs thermochronological research in the Rocky Mountains, in addition to studying the timing of impact events on the Moon by using a laser microprobe to date NASA Apollo mission samples.
 
(Ph.D. studies, ASU School of Earth & Space Exploration, 2016-2021)
Soumya measures Fe isotope fractionation and Si isotope composition in achondrite meteorites. Her Fe isotope work on aubrites, in particular, has provided new insight into the formation of metal nodules in these unique meteorites. She recently authored the article "Women Astronauts? How Ridiculous!" for the ASU Interplanetary Initiative Community in a Box Project.
 
Dr. Stephen RomanielloStephen Romaniello
Gerald D. Sisk Associate Professor of Isotope Geochemistry, University of Tennessee
(Academic Professional, ASU School of Earth & Space Exploration, 2012-2019)
Dr. Romaniello develops cutting edge applications of nontraditional stable and radiogenic isotopes in sedimentology, cosmochemistry, and medicine. The core of his research addresses how the Earth’s chemical and biological evolution has played out over the past 3.8 billion years.
 
Staff Scientist, Los Alamos National Laboratory
(Ph.D. studies, ASU School of Earth & Space Exploration, 2007-2012)
Dr. Sanborn analyzes nucleosynthetic anomalies to decipher petrogenetic histories of meteorites and the evolution of their associated parent bodies in the early Solar System, and determines isotopic constraints on the formation of the first solids and planetesimals.
 
 
Research Geologist, USGS Geology, Geophysics, & Geochemistry Science Center (Research Assistant Professor, ASU School of Earth & Space Exploration, 2014-2016) Dr. Souders' research integrates mineral geochemistry and geochronology to understand the origin and evolution of Earth's crust and differention of the mantle, and the provenance and diagenesis of detrital heavy minerals.
 
 
(M.S. studies, ASU School of Earth & Space Exploration, 2017-2019)
Gabriel's research involves the development of new analytical methods for the measurement of stable strontium isotopes, including laboratory geochemistry and multi-collector plasma mass spectrometry.
