Greg Brennecka (Ph.D. Student, School of Earth and Space Exploration)

M.S., Oregon State University (2006) – Greg is studying uranium isotopes in early Solar System materials to better understand the conditions and timing of events in the solar nebula. He is investigating the extent of uranium isotope variation in the Solar System, the reasons for the variations, and the effect those variations have on Pb-Pb ages.

Matthew Sanborn (Ph.D. Student, School of Earth and Space Exploration)

B.S., Arizona State University (2007) - Matt's current research involves measuring trace elements and isotopic compositions of a particular class of differentiated meteorites, the angrites, to try and understand the petrogenetic processes that occurred in the early Solar System.

Lev Spivak-Birndorf (Ph.D. Student, School of Earth and Space Exploration)

M.S., University of Pittsburgh (2007) - Lev studies the origin and evolution of solar system materials using stable and radiogenic isotope techniques. Specifically, he investigates the chronology of differentiated meteorites using extinct radionuclide chronometers in order to understand the timescales of geologic processes in the early Solar System. He also uses stable isotope measurements of Boron to study aqueous processes in the crust of Mars as represented by Martian meteorites.
