Resumen: Manifolds arise in many areas of mathematics and science, for example as the solution set of certain equations, the state space of a physical system, or as a model for the universe. The study of manifolds and their properties has been a driving force behind topology for many decades. In this lecture I will explain the idea that the collection of all manifolds may itself be regarded as a kind of space, a moduli space, and that such spaces have interesting and useful properties.

Resumen: Scanning is a remarkably successful method for understanding the topology of moduli spaces. I will explain the method with some examples, some classical and some more recent.

Resumen: Moduli spaces of manifolds often arise in families, indexed by some number g. For example, there is a moduli space of genus g surfaces for each natural number g, and similar patterns appear for manifolds of higher dimension. In recent joint work with Oscar Randal-Williams, we prove that such moduli spaces often exhibit homological stability: the cohomology of the moduli space is independent of g, in a range of degrees that grows linearly with g.
