Dr. Jarvis’ research interests lie in the field of Geodynamics. He employs computer intensive numerical models to study the temperature and velocity fields in the solid outer 3,000 km of the Earth’s interior. This research addresses the problem of the driving force for plate tectonics and continental drift. Numerical studies of the causes and consequences of continental collisions, aggregation and dispersal form a part of this research. It involves the use of microcomputers, UNIX workstations and supercomputers.
