Dr. Sachiko Amari
Sachiko Amari received her Ph.D at Kobe University in Japan in 1986 for the study of noble gases of extra-terrestrial material in deep-sea sediments. She worked as a research associate in the Chemistry Department at the University of Chicago for 2 years starting in 1988. There with Drs. Edward Anders and Roy S. Lewis she developed a procedure to extract carbonaceous presolar grains from the Murchison meteorite. She joined our group in 1990 and is currently working as a senior research scientist. Her work has been mostly devoted to isotopic analyses of presolar grains and their interpretation.
Research Interests Sachiko Amari is interested in the characterization of presolar grains and probing the events that occurred in the early solar system by using isotopic information.
