By means of chemical abundances of stars at the solar neighborhood, we attempt to reconstruct the star formation history of the Milky Way over the last 13 Gyr. We are able to identify key features in the star formation history of the Galaxy using a best-fit SFR, particularly an initial starburst at very early times and a distinct dip in the rate of star formation after several Gyr. We explore how different star formation histories impact on the chemical signatures of stars of different ages. We also note the importance of choosing the correct theoretical yields in order to fit the data well.
