Current Research Activities
Seismic Cycle
Observations and models of coseismic, postseismic, interseismic, and long term deformation processes
Glaciology
Glacier flow, variability at different timescales (e.g.,
seasonal and tidal periods), basal mechanics, ice rheology
Geodetic Science
Development and application of InSAR and GNSS analysis techniques, including strain maps, time series analysis, transient detection, noise reduction, and open software development.
Geophysical Inverse Problems
Bayesian approaches to geophysical inverse problems,
use of sparsity-inducing approaches and multi-scale
field analysis.
The Advanced Rapid Imaging and Analysis (ARIA) Project
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.

The NASA-ISRO SAR (NISAR) mission
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.
