Research Interests- Fault mechanics
- Models of crustal deformation
- Rheology and thermal structure of continents
- Paleoclimate
My primary scientific interest focuses on the mechanics of faulting throughout
the earthquake cycle. I am interested in providing insights into the
earthquake cycle from both data-oriented and model-oriented perspectives.
I utilize seismic and geodetic data sets in my work. I use several data
processing techniques including high-resolution earthquake relocation
techniques (hypoDD), GPS data processing with GAMIT/GLOBK and InSAR
processing with ROI_PAC. I numerically simulate time-dependent tectonic
processes using 2-D and 3-D finite element models to quantify the partitioning
of deformation between seismic and aseismic processes and to explore the
rheology of the crust and mantle.
