Biography

Andy Hooper has been Professor of Geodesy and Geophysics at Leeds since May 2013 and is currently Co-Director of the Institute of Geophysics and Tectonics. He has pioneered the development of new algorithms to accurately extract deformation of the ground from time series of satellite radar images, which are now widely used in the community (StaMPS). He has also developed new methods for modelling the volcanic and tectonic processes that lead to ground deformation. He led the geodetic monitoring from space and subsequent modelling for the 2010 and 2014 Icelandic volcanic eruptions and also discovered a new link between ice cap retreat and volcanism there. He also led the long-term deformation effort in the €6M European FUTUREVOLC project, which established an integrated volcanological monitoring procedure in Iceland through European collaboration. In 2016 he was awarded the James B. Macelwane medal by the American Geophysical Union, given to outstanding early career scientists who have shown depth, breadth, impact, creativity and novelty in their research
