Dr. Laurence Gray is currently an Emeritus Scientist at the Canada Centre for Remote Sensing (CCRS) and an Adjunct Professor in the Department of Geography at the University of Ottawa.
Beginning in 1975, Dr. Gray worked at CCRS on the development of both the technology and applications of microwave remote sensing. His early contributions include the demonstration of imaging radar for operational sea ice reconnaissance, but mostly Gray has been recognized for his work in the field of SAR interferometry. In 1990 he proved that relative movement within a SAR scene could be recovered with interferometric techniques to a fraction of a wavelength. Subsequently, he developed both airborne cross-rack and along-track interferometric SAR (InSAR) systems for mapping topography and moving targets.
Currently, Dr. Gray works on the application of satellite data for monitoring change in the cryosphere, such as using RADARSAT data from the Antarctic Mapping Mission to map previously unknown ice streams and tributaries in Antarctica, and to reveal subglacial water movement through quantifying 3-dimensional movement of the surface of glaciers and ice streams. His current interests include the use of satellite radar data (e.g., Radarsat, Cryosat) to monitor and understand cryospheric change in both the Arctic and Antarctic. He has also worked on a number of advisory and review groups for the European Space Agency, NASA and the US National Science Foundation.
