My research, particularly evident in studies focused on the Chilean subduction zone, centers on deciphering the intricate mechanics of earthquake processes and their impact on the Earth's crust. A key aspect involves leveraging continuous GPS data to precisely determine the coseismic slip during major earthquakes, as demonstrated in our 2016 analysis of the Mw 8.3 Illapel event. This allows us to visualize how the fault ruptures and the subsequent afterslip, providing critical insights into the earthquake cycle and the viscoelastic response of the region.

Beyond individual events, I am also keenly interested in the longer-term tectonic controls on seismicity. Our 2019 work highlighted a compelling correlation between the curved geometry of the subducting Nazca plate and the observed segmentation of earthquakes in northern Chile. This suggests that the shape of the plate boundary significantly influences where and how large ruptures occur.

In essence, my research in this area aims to integrate precise geodetic observations with geological understanding to unravel the complexities of earthquake generation and crustal deformation in subduction zones. By characterizing slip behavior, investigating the influence of plate geometry, and examining the interaction between different fault systems, I strive to contribute to a more comprehensive understanding of these dynamic and often hazardous regions. My work ultimately seeks to improve our knowledge of the fundamental processes governing earthquakes in subduction zones.
