Yajing Liu is a graduate student in the Department of Earth and Planetary Sciences, Harvard University. Her Ph.D. thesis, advised by Professor James R. Rice, focuses on the physical mechanisms of aseismic deformation transients and relation to tremor activities in subduction zones. She is generally interested in the source physics of aseismic and seismic events, loading processes and crustal deformation throughout earthquake cycles, and the fault material properties, using numerical modeling, as well as geodetic and seismic observations. Before coming to Harvard, Yajing received a B. Sc. (geophysics) from Peking University, Beijing, China, in 2001, with a thesis on the FEM simulation of deep earthquake mechanisms.
