Research Interests

Dr. Pratt has been actively researching new methods in seismic wave modelling and imaging. He and his students have developed a number of innovations in these areas that make possible large scale forward and inverse modelling of exploration seismic data through numerical simulation of the full wave equation. Together they have been able to use these methods in imaging structures in a wide range of applications, from small scale site investigations to wide angle crustal seismology.
