B.Sc. 1974 University of Western Ontario in London, Canada

Ph.D. 1979 Scripps Institution of Oceanography, University of California, San Diego.

1979­ - 1992 NASA Jet Propulsion Laboratory, Pasadena, California.

1992 - ­2010 University of Miami, co-­founder of the Center for Southeastern Tropical Advanced Remote Sensing (CSTARS)

2011 - Present USF Department of Geology, then USF School of Geosciences. Distinguished Lecturer for the American Association of Petroleum Geologists (2006­2007), is a Fellow of the American Geophysical Union and the Geological Society of America (GSA), received a GSA “Best Paper” award in 2006, and received GSA’s Woollard award in 2010.


My research uses satellite geodesy and remote sensing data (GPS, InSAR) to study Earth surface and sub­surface processes, including earthquakes and volcano deformation, mountain building, coastal subsidence, ground water extraction and glacier motion.
