InSAR theory and algorithms
My research is driven by one main passion: making the most of modern geodetic datasets, especially interferometric synthetic aperture radar (InSAR) measurements, to understand the changes on Earth’s surface.
Tectonic processes
InSAR has been our trusted companion in monitoring surface movements linked to tectonic processes since the landmark 1992 Landers Earthquake. With the support of the latest and upcoming SAR constellations, we can detect even the subtlest shifts in Earth’s movements. I’ve always been deeply fascinated by the tectonic dances of our planet. One of the central goals of my research is to understand earthquake and volcanic processes through the lens of SAR.
Environmental and Sustainability Applications with InSAR
InSAR is not just about measuring target motion. InSAR has this keen sensitivity to changes in things like soil moisture, the lushness of vegetation, and the intricacies of canopy structures. I’m eager to delve into how InSAR can help in diverse earth observation areas.
