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.
