RESEARCH
The primary goal of my research is to better image the structure of the
earth’s crust and mantle in order to gain insight into the physical
and chemical factors associated with internal geodynamic processes.
Questions of particular interest include the nature of tectonic
processes involved in the buildup and subsequent modification of
continental and oceanic lithosphere; the determination of mineral and
fluid-phase reactions in tectonically active regions; and the
implications of core-mantle boundary properties on large-scale mantle
circulation. In my research, I integrate new approaches to
modelling seismic data with high quality broadband waveform data
sets, including those from temporary seismometer arrays.
