I use the rich source of information contained in the atmosphere of stars, gained through the analysis of their spectra, to contribute to the advancement of:
Chemical Evolution of the early Galaxy
Formation, assembly history, of the Milky Way
Spectroscopic models of stars
Precise stellar characterization - Stellar parameters and abundances
Chemical Evolution of the early Universe, via the analysis of extragalactic stars
Characterization of Planet hosts and what can the stellar chemistry tell us about their planets
