"The Star Formation and Metallicity History of Galaxies"

Observing the star formation rate and metallicity since the earliest times
in the universe is crucial to understanding galaxy formation and
evolution.  I present the results of our large observational investigation
into the star formation and metallicity history of star-forming galaxies
between 0<z<3.  I compare our observed metallicity history with
predictions from cosmological hydrodynamic simulations, and discuss the
future directions for our star formation and metallicity history research.
The goal of this research program is to gain a simultaneous observational
understanding of the metallicity and star formation history of galaxies
between 0<z<3 to confront cosmic chemical evolution models.
