Prof. Amari works on separation and isotopic analyses of presolar grains in meteorites. Laboratory studies on presolar grains, stardust born before the solar system, can provide a wealth of information on nucleosynthesis in stars, mixing of stellar ejecta, and the Galactic chemical evolution (temporal variations of elemental and isotopic abundances in the Galaxy). More information about presolar-grain research in our group can be found in the group website at http://presolar.wustl.edu/
She is also interested in how volatiles were acquired in the solar system. I work on concentrating and isolating the carbonaceous matter that contains most of Kr and Xe in primitive meteorites.
