Personal profile

Biography

My research uses geophysics, primarily seismology, to increase our understanding of the structure and processes occurring within the Earth’s subsurface. This research is mainly focused on the structure of the lithosphere, i.e. from the surface to depths of about 250 km, using seismic waves generated by distant earthquakes. I have helped conduct several large-scale seismic experiments in North America, including broadband deployments in British Columbia, the Southern Rocky Mountains and Central California. I have also participated in an active-source seismic experiment at Mount St. Helens using nodal geophones. This work increased my research interest in active volcanos, particularly their structure and the different types of earthquakes that they produce. I am also interested in advanced data processing methodologies and the modeling of seismic wave propagation, both of which can be leveraged to further our understanding of the Earth.
