Research Interests
The current research of Professor Bernatowicz focuses on detailed laboratory observations of presolar grains (literally ancient stardust) from meteorites to draw inferences about the physical conditions in ancient circumstellar environments and about the formation of dust in the Galaxy. His research utilizes isotope mass spectrometry and transmission electron microscopy (electron diffraction, electron energy loss spectrometry and energy dispersive X-ray spectrometry).
