My research focuses on developing new time-series radar interferometry techniques for studying temporal characteristics of surface deformation due to various geophysical phenomena. I'm particularly interested in the multi-dimensional phase unwrapping problem and its application to improving surface deformation estimates from Persistent Scatterers (PS) and Small Baseline (SBAS) techniques. I work with Prof. Mark Simons and primarily, apply my techniques to study the aseismic creep across the Central San Andreas Fault.
