Physical quantities are often computed perturbatively in a small coupling leading to divergent asymptotic series. I will explain how techniques from resurgence allow one to identify piece-wise analytic structures behind these asymptotic expansions. The analytic structures encode non-perturbative physics and often a dual asymptotic expansion can be accessed. I will explain this in the context of exact WKB and topological string theory.
