Theoretical and Observational Seismology
The primary goal of Professor Wen's group is to discover and map seismic
in the Earth's interior and to understand these seismic structures in
the context of composition, temperature and dynamics of various
parts of the Earth.
Professor Wen also develope hybrid methods and migration
Hybrid methods are combinations of analytical and numerical methods,
with numerical methods applied in heterogeneous regions only and
analytical methods outside.
Professor Wen's group's research in geodynamics is directed at
understanding the relationship of
large scale geodynamical observables (geoid, topography,
plate motions and
intra-plate stresses) with mantle rheology and convection.
causes lateral variations of chemistry and temperature in the mantle and
those lateral variations eventually drive mantle convection and produce
signatures which are observable at the surface of the Earth.
Most of the efforts in geodynamics is to
understand deep mantle processes using constraints from those surface
observables and seismic results. The research projects include:
