The properties of globular clusters observed today reflect both the conditions of globular cluster formation but also the physics of globular cluster survival. Recent theoretical work has shown a strong connection between a galaxy's formation and assembly history and the distribution of the galaxy's globular clusters in age-metallicity space. Due to the age-metallicity degeneracy in the optical, reliably measuring extragalactic globular cluster ages has been observational challenging. I will present a novel method that combines optical photometry and near-infrared spectroscopy to provide ages for large samples of globular clusters. I will present results from applying this technique to data from the SLUGGS survey and to GCs around M31. I will also look to the future and discuss how forthcoming wide field surveys such as LSST will provide a volume limited sample of globular cluster systems.<br class=""><br class=""><a href="https://www.albanova.se/event/astronomy-seminar-via-zoom-chris-usher/" class="">https://www.albanova.se/event/astronomy-seminar-via-zoom-chris-usher/</a><br class=""><br class="">We will have the colloquium using zoom.
