Peer review is a cornerstone of modern academic publishing practices, but researchers seldom receive any formal training on how to actually do it. This workshop provides an introduction to essential peer review skills, and a template to guide you on your way to producing useful peer reviews. It is aimed at published researchers who have started to receive review requests from journals or colleagues. Attendees will learn about the general peer review process, and how to write fair, constructive, and actionable reviews of others' work. Improving your peer review skills will also improve your own writing skills, and help you to think about your own work from the perspective of a peer reviewer.
