Appointment
- Reader in Seismology
- Dept of Earth Sciences
- Faculty of Maths & Physical Sciences
Biography
After PhD at California Institute of Technology, I enjoy my time as a postdoc in DTM at Carnegie Institution of Washington and as a Scientist at IFREE, JAMSTEC in Japan. As a "free-style" seismologist generally, I strive to use critical seismological observations along with relevant theoretical and numerical grounds to uncover fine details of the Earth's interior and discuss/validate relevant processes operating on the planet and governing earthquakes/volcanic/environmental forcing.
Research Summary
Observational seismology focusing on analytic and numerical wave propagation modeling of broadband waveform and investigation of isotropic/anisotropic Earth structure relevant to plate tectonic processes and fast/slow earthquake behaviors near plate boundary. My continuing effort is to develop critical seismic observations and untangle tectonic/volcanic processes operating over different spatial and temporal scale.
Current efforts include:
- Volcano seismology: broadband seismic/geodetic observations vs. the interaction/feedback between volcanic conduit and magma chamber.
- Seismic anisotropy in the core-mantle boundary region.
- Hydration, compositional mixing/unmixing in the transition zone/uppermost lower mantle vs. long-term plate motion history.
- Repeating/clustered earthquakes vs. Source scaling.
- The nature of sub-slab and asthenosphere fabric; small-scale heterogeneity/anisotropy in the oceanic lithosphere.
- Structural control of large/slow earthquakes in plate boundary.
- Broadband seismic constraints of large earthquakes.
Teaching Summary
I am teaching 3rd year module Seismology I in since Fall 2014-2015. The module covers basic principle of modern seismology. After introduction of the history of seismology and instrument, the module will go through fundamental components of seismic wave theory, source theory and the use of seismic observations in constraining Earth's interior and earthquake source property. This module will be followed by another new module Seismology II by Dr. Ana Ferreira. I also co-tutor Field Geophysics module.
