Our universe appears to be mostly made up of two mysterious substances: dark matter and dark energy. This symposium will focus on finding out more about these components, including alternative explanations of the data. We will discuss probes of the geometry and growth of structure in the universe including type Ia supernovae, baryon acoustic oscillations, redshift space distortions, cosmic shear and cluster counts. Both the statistical power and potential systematic limitations of different approaches will be considered. We will conclude with an overview of current and future observational surveys.
