Raphaël Grandin obtained a master of science degree in executive engineering at École des Mines de Paris and a Ph.D. at Institut de Physique du Globe de Paris (IPGP). He held a position of teaching assistant at University of Paris, was a postdoctoral fellow at École Normale Supérieure de Paris, and is now an associate professor at University of Paris and IPGP.
Raphaël studied a variety of geophysical problems related to seismology, rifting and magmatic processes, and earthquake source models using space-based geodesy. It is with innovative advances in the methods and applications of interferometric synthetic aperture radar (InSAR) that his scientific contributions stand out.
His early work on the Ethiopian rifting episode of 2005–2009 provided an unprecedented account of the entire sequence of events, placing constraints on tectonic stress, magmatic pressure, and the time-dependent migration of magma between deep and shallow reservoirs. In the Himalaya, he used innovative data correction methods to extract the uplift velocity profile across the range, highlighting the stepwise migration of crustal ramps to the mountain front.
What characterizes Raphaël’s work is a combination of fine observations and the development of innovative physical interpretations of the processes behind those observations. This is exemplified in the study of recent earthquakes, from both tectonic (Nepal, 2015; Chile, 2012) and man-made (Oklahoma, 2016) origins.
Raphaël is also a dedicated mentor and teacher. He contributed to the development of community InSAR software and serves as scientific advisor for the Centre National de la Recherche Scientifique (CNRS) Solid Earth Data Center in France. He received citations for excellence in refereeing from the editors of two AGU journals in 2013 and 2014 and of Earth, Planets and Space in 2015.
We are thrilled to see Raphaël’s achievements recognized by the 2019 John Wahr Early Career Award.
