Research Subject(s)
My research interests encompass earthquake and fault kinematics over seismic cycles, seafloor geodesy, and geodetic imaging of transient deformation in the lithosphere.
Key Words
Crustal deformation / Seafloor geodesy / Seismic cycle / Rheology / Fault kinematics
Research Activities

I study seismic and aseismic processes in various tectonic contexts, spanning from inland continental faults to subduction zones, using Global Navigation Satellite System (GNSS), satellite imagery (e.g., InSAR), and seafloor geodetic observations. I am particularly interested in understanding the role of aseismic deformation in balancing seismic budget across plate boundaries, modulating the spatiotemporal distribution of stress in the lithosphere, and shaping the seismic patterns in the crust. All these mechanical processes have profound implications for current seismic risk assessment frameworks.
