Juliet Biggs MAE is a British geologist who is Professor of Earth Sciences at the University of Bristol. Her research uses satellite data, particularly Interferometric Synthetic Aperture Radar (InSAR) to understand earthquakes and volcanoes and the hazards they pose. She was awarded the American Geophysical Union John Wahr Award in 2017 and a European Research Council (ERC) consolidator grant in 2020.
Juliet Biggs was born in Ascot, Berkshire and attended Coworth Park Primary School, Sunningdale and the Lady Eleanor Holles School in Hampton. Both her parents were academic mathematicians Norman L. Biggs and Christine Farmer. She studied geology as specialism in Natural Sciences at the University of Cambridge. As an undergraduate, she did summer research internships at the University of Southampton and Caltech. She moved to the University of Oxford as a doctoral researcher, where she studied the earthquake cycle at the Denali Fault. During her doctoral research supervised by Barry Parsons and , Biggs used interferometric synthetic-aperture radar (InSAR) to determine strain around faults. This strategy has been adopted by InSAR researchers around the world.
During her postdoctoral research, Biggs started working with satellite imagery to understand volcanoes. In 2010, Biggs joined the University of Bristol, where she was made a full professor in 2019. Her research investigates earthquakes, volcanoes and the earthquake cycle, especially in the East African Rift and Latin America. where she has identified that several volcanoes previously considered dormant are in fact evolving rapidly.. In 2020, she was awarded a European Research Council Consolidator Grant to image volcanoes using 'strain tomography'.
