Bradley Garrett is an American social and cultural geographer based at the University of Sydney, whose work involves 'finding the hidden in the world', and lies at the intersections of cultural geography, archaeology and photography. His first book, Explore Everything: Place-Hacking the City, was an account of his adventures trespassing into ruins, tunnels and skyscrapers in eight different countries. He writes for, among others, the Guardian, and his work has been featured in media outlets worldwide, including Channel 4, ITV and the BBC in the UK. Garrett was a postdoctoral fellow at Wolfson College, Oxford, and has been an invited speaker at the Festival of Dangerous Ideas at the Sydney Opera House (Australia), Chicago Ideas Week and Google Zeitgeist (USA), and at the Tate Modern and Barbican galleries (UK).
