Understanding the formation and evolution of cosmological structure is one of the most pressing challenges in modern astrophysics. The last decade has seen a rapid improvement in our ability to observe galaxies, galaxy clusters, and the cosmic web – a change that requires corresponding gains in our ability to model these structures in order to understand them. In this talk, I will discuss my efforts to understand cosmological structure formation using large-scale numerical simulations. I will explain the fundamental methods used to model these systems, and will show recent results from simulations of galaxy clusters – in particular, results that include sophisticated physical treatments of the intracluster medium and of gravitational lensing.
