(1990) in Geophysics are from Princeton University, and he received his B.Sc. (1988) in Geophysics from the University of Utrecht in the Netherlands, of which he is a native.
Tromp’s primary research areas are in Theoretical & Computational Seismology. Research topics include: surface waves, free oscillations, body waves, seismic tomography, numerical simulations of 3-D wave propagation, and seismic hazard assessment. In collaboration with the late Princeton Geosciences faculty member Tony Dahlen he published the book Theoretical Global Seismology.
