"Understanding the evolution of the Milky Way disk and bulge with the GALAH survey and HERMES spectrograph(End-of-thesis colloquium)"

The formation and evolution of spiral galaxies is a research topic central to modern Astronomy. In this context, the Milky Way offers a unique opportunity for astronomers to study a spiral galaxy in detail and thus informs many aspects of galaxy formation theory. The observational signatures of Galactic stellar components provide clues to its assembly history. This thesis is focused on two main components of the Galaxy: the stellar disk and bulge. In particular, we examine the chemical properties of these components and their implications for Galactic evolution.
