Juliet received B.A. and M.Sci. degrees fromthe University of Cambridge, (2003), and a Ph.D.from the University of Oxford (2007). After a brief time in the US, she moved to the University of Bristol in 2010, becoming a full professor in 2019. Juliet has worked on earthquakes in all tectonic settings and all phases of the earthquake cycle. Through major multidisciplinary projects in the East African Rift, she has studied how dyke intrusions and faulting accommodate extension and the role of magma transport and storage, providing a scientific basic for new hazard assessments and building codes. In volcanology, she has found that numerous volcanoes previously considered dormant are actually restless and estimated the intrusive and extrusive fluxes that contribute to edifice building and continental growth. Working with the Bristol Visual Information Laboratory, she has pioneered the application of deep learning algorithms, changing the ways in which volcanoes are monitored and deformation signals interpreted. Recent projects are adapting these methods to for the UK's Digital Environment, using machine learning and satellite data to monitor deformation at abandoned mines and railway embankments. She is currently Deputy Director of the BGS Centre for the Observation and Monitoring of Earthquakes, Volcanoes and Tectonics (COMET). She received the Bullerwell award of the British Geophysical Association in 2016, the Lloyds of London Science of Risk Prize in 2016 and the AGU John Wahr Early Career Award in 2017 and a Leverhulme Prize in 2018. She will start work on an ERC Consolidator Project in 2022.
My research primarily uses Interferometric Synthetic Aperture Radar (InSAR) to understand the physics of the processes that deform the earth's surface. Recent developments in satellite geodesy are providing a new perspective on continental tectonics and volcanic processes through observations of aseismic processes such as interseismic strain accumulation, postseismic relaxation and magma intrusion.
These measurements can identify the mechanisms controlling continental deformation and quantify the constitutive laws controlling rheology. My current areas of interest are the East African Rift and the volcanoes of Central America and the Northern Andes. Practical applications of my work include seismic and volcano hazard assessment and geothermal resources.
