Jean Virieux is a Professor of Geophysics at the Université Grenoble Alpes. His research interests cover topics on seismic wave propagation for seismic source modelling and for seismic imaging. Both kinematic and dynamic finite earthquake sources are of interest to him in order to better predict ground motion. Both active seismic field related to seismic exploration and passive seismic monitoring related to geodynamics or reservoir tracking have concentrated his modelling effort. A few key words may be listed where he has made contributions: seismic tomography; numerical modelling (Finite Difference, Finite Volume), dynamic rupture modelling of earthquakes, ray theory, ray seismograms, asymptotic theory of wave propagation, waveform inversion (Born or Rytov approximation), inverse problems.
