This webpage is not at all dedicated to my seismology research, but if you are interested, you can visit my seismology research webpage.

In summary, I worked on earthquake source physics through observational seismology. In particular I was interested in slow earthquakes, and how we can use transient kinds of seismic activity to learn more about end member types of seismic activity.

I was also very interested in finding ways to study earthquakes on the electromagnet spectrum. Although this can be difficult due to challenges with adequate instrumentation, I think this may be promising for earthquake prediction. I think about when I rub a sock against a carpet — it generates a static electric charge. When you touch something else — that static electric charge is released. It reminds me of earthquakes; if there is pre-slip and there are materials along the fault interface that can generate a static electric charge, they may do so — generating an electric field from the potential energy from the static electricity that could potentially be measured. Then, when the earthquake occurs, that electric field would discharge.

This could explain why we see lightning coming from faults during earthquakes at night, or why animals sometimes behave strangely before a large earthquake (we know they are sensitive to EM fields — dogs for instance align with magnetic fields when they take shits). I digress. My peer reviewed publications are below, and this is my Google Scholar profile.
