Stephen Coulson has more than 20 years of experi- ence in the field of satellite Earth observation and its applications, the last 18 of which have been with the European Space Agency (ESA). In the early 1990s, he worked on the development of processing facilities to deliver ocean wind, sea-surface height and wave spec- tra for national meteorological offices within three hours of sensing for the ERS-1 and ERS-2 satellites. Throughout the 1990s, he coordinated a group of scien- tists around the world to develop the technique of syn- thetic aperture radar (SAR) interferometry for the production of digital elevation models (DEMs) and displacement maps of the Earth’s surface for earth- quakes, landslides and subsidence events. Since 2000, he has managed an ESA program to support the devel- opment of the European Earth observation services industry and is now head of the Industry Section within the Directorate of Earth Observation Programs in the European Space Research Institute (ESRIN) in Frascati, Italy. Stephen earned a degree in physics from the University of Durham and a PhD degree in theoretical physics from the University of Southampton, both in England.
