Brendon Bradley has made significant contributions in several important areas of earthquake science and engineering. In particular, his contributions have focused on first-principles approaches to ground-motion prediction, seismic hazard analysis, and performance-based earthquake engineering. His most notable contributions have involved the development of improved methods for earthquake-induced ground motion selection, validation of empirical and simulation-based methods of ground motion prediction, and the interrogation and interpretation of ground motion observations in large earthquakes. His disciplinary research has also been acknowledged through receiving the 2016 Prime Minister’s Emerging Scientist Prize, 2013 Rutherford Discovery Fellowship, and five Marsden Fund grants. As a research leader, he co-led the establishment of QuakeCoRE as a centre of research excellence, which he currently leads as its Director. As a science communicator, he has had a major role in the dissemination of lessons from the 2010-2011 Canterbury and 2016 KaikÅura earthquakes.
