The growth of cosmic structure provides a unique approach for measuring the dynamic evolution of dark energy and distinguishing different models of gravity. In this talk, I will focus on two of the most important methods for measuring the growth of structure: galaxy cluster counts and the redshift-space distortions of galaxy clustering. I will discuss the systematic uncertainties involved in both methods, and how I use numerical simulations to help reducing these systematics and improve our theoretical predictions.
