In the ICGL, Nicole measured the Cr and Ti isotope composition of achondrite meteorites to better constrain the formational timeline of rocky bodies in our Solar System. She wass particularly interested in using mass-independant isotopic anomalies (eg 50Ti and 46Ti) in carbonaceous chondrites to model the nucleosynthetic reservoirs from which they may have been sourced.
