My research interests are focused on developing a better understanding of the physical and chemical processes that shaped the origin of our solar system from the condensation of the first solid materials to the evolution of planetary bodies. I conduct this research primarily by measuring the chemical and isotopic compositions of primitive meteorites and cosmic dust using secondary ion mass spectrometry (NanoSIMS and conventional ion probe). I apply similar techniques to develop new and better tools for nuclear forensics and attribution.
