A recurring theme in topology is to determine the geometric and homological finiteness properties of spaces and groups. A fruitful approach is to compare these finiteness properties to those of differential graded algebras that model topological objects of this sort. I will discuss several concrete questions that arise in this context, and explain how the cohomology jump loci help answer some of those questions.
