Research interests
I use stardust to study the origin of the elements by stellar nucleosynthesis. Tiny (<10 µm in diameter) grains of silicon carbide, graphite and other refractory minerals and rocks condensed around dying stars (mostly red giant stars and supernovae), survived potentially destructive processes in the interstellar medium and during solar system formation, and can now be found in meteorites. These grains preserve an isotopic record of the nucleosynthesis in individual stars. We measure the isotopic compositions of these grains by a new technique, resonant ionization mass spectrometry, developed by my collaborators at Argonne National Laboratory. We are now building a new instrument at the University of Chicago, the ion nanoprobe, which will allow isotopic and chemical analysis at finer scales than any instrument now available. Among other things we will use this instrument to study cometary dust and contemporary interstellar dust returned to Earth by the Stardust spacecraft in 2006.

I also use the isotopic compositions of refractory inclusions in meteorites to study the earliest history of the solar system. Short-lived chronometers such as the 26Al-26Mg system can resolve time differences of only a few tens of thousands of years for events that occurred 4.55 billion years ago. Isotopic fractionation effects and the relative abundances of trace elements are used to constrain thermal histories and redox conditions in the solar nebula and on the asteroidal parent bodies of meteorites.
