Matthew Champion is a Senior Lecturer in History in the School of Historical & Philosophical Studies at the University of Melbourne. Before returning to Australia, he held posts at St Catharine's College, Cambridge, and Birkbeck, University of London. His first book, The Fullness of Time: Temporalities of the Fifteenth-Century Low Countries (University of Chicago Press, 2017), was the recipient of the 2018 Gladstone Prize of the Royal Historical Society. His current research, funded by the Australian Research Council, examines the history of the sounds we associate with time – from bird song to the hum of freeways, from the silence of the hourglass to clocks that play musical alarms.
