I use satellite remote sensing methods to investigate physical volcanic processes.  I am interested in volcano deformation and degassing, in terms of their significance both for hazard assessment and for understanding volcanic systems.  My past work has concentrated on volcano deformation on the Central American Volcanic Arc, including measurements of slow gravity-driven flank movement at a stratovolcano and of large topographic change associated with lava dome extrusion. 

My role in STREVA is to use satellite remote sensing, particularly InSAR measurements of volcano deformation, to monitor activity at both ‘forensic' and ‘trial' volcanoes in the Lesser Antilles, Ecuador and Colombia.  The production of high resolution time series of deformation from past phases and, from 2013 onwards, of current activity, will feed into Work Package 1's goals of developing forecasting tools from real-time data.
