Current Research Activities
Observations and models of coseismic, postseismic, interseismic, and long term deformation processes
Glacier flow, variability at different timescales (e.g.,
seasonal and tidal periods), basal mechanics, ice rheology
Development and application of InSAR and GNSS analysis techniques, including strain maps, time series analysis, transient detection, noise reduction, and open software development.
Bayesian approaches to geophysical inverse problems,
use of sparsity-inducing approaches and multi-scale
A joint Caltech / JPL project to provide state-of-the-art
geodetic products and derived geophysical models for both science and
emergency response communities, while emphasizing speed, automation and technical rigor.
A dedicated L-band radar satellite for
studying hazards and global environmental change. On the science
definition team, I serve as the solid
earth science co-lead, with focus on the seismic
cycle, glaciology and hazard response.
