Research Focus

I am a geodesist specialized in microwave remote sensing with broad interests monitoring Earth’s surface deformation phenomena using satellite geodesy. My research focuses on developing new methods and algorithms for the advancement of various satellite imaging techniques acquired by new generation Synthetic Aperture Radar (SAR) sensors. Main interest exploring Interferometric SAR (InSAR) capability by integrating with other remote sensing data for analyzing and mitigating impacts of various natural and anthropogenic hazard phenomena.
