I am a Ph.D. candidate in geophysics at the Caltech Seismo Lab, working with Zhongwen Zhan and Mark Simons. In my research, I use seismic and geodetic techniques to study the mechanical behavior of Earth's crust. My projects span from the basin scale (near-surface elastic heterogeneity, site amplification, hydrogeologic monitoring) to the plate scale (tectonics, structure, fault mechanics). Much of my work focuses on the earthquake and engineering seismology applications of distributed acoustic sensing (DAS), an emergent technology that converts fiber optic cables into dense arrays of broadband strainmeters. I am also interested in marine geophysics, especially the physics of microseism generation.
