Professor Justin Revenaugh
Justin uses earthquake waves to image deep Earth structure. The tools he uses are derived from techniques pioneered in the oil industry and designed to detect and characterize abrupt variations in material properties, such as discontinuities associated with phase changes, scatterers created by faulting and jointing of the crust, and slab dregs near the core-mantle boundary.
Associate Professor Maximiliano Bezada
Max has been with the department since 2014. His primary research interests include subduction processes and the creation, destruction and modification of the continental lithosphere, as well as deep seismicity and intracontinental seismicity. He approaches these problems primarily through imaging of seismic velocity, anisotropy and attenuation structure.
Postdoctoral Researchers
Joseph Byrnes
Joseph Byrnes has been with the department since getting his PhD at the University of Oregon in 2017. He currently works with Max Bezada on ways to measurement seismic attenuation in the upper mantle, and uses the results study the lithosphere-asthenosphere system. He also works on events at the KPg boundary and techniques for imaging the upper 10s of meters of the Earth.
Aaron Hirsch
Aaron, originally from Minnesota, joined the department after getting his PhD at the University of Rhode Island and Masters at Boston University. He uses "big data" and super computing resources to perform ambient noise and earthquake full-waveform inversion tomography of the lithosphere and upper mantle in a diverse range of tectonic settings. Additionally, Aaron has expertise in active source seismic techniques gained from his time as a geophysicist at ExxonMobil.
Graduate Students
Hwaju Lee
Hwaju Lee joined the department in 2015 after receiving a M.Sc from the University of Pennsylvania and she is the one the first generation of Max Bezada's students. Her main research interest is seismic anisotropy in the mantle. She is currently working on incorporating seismic anisotropy into tomographic imaging of the western Mediterranean.
Meng Sun - Now Graduated!!
Meng has been working with professor Bezada since 2015. Her primary research interests focus on the mechanisms responsible for intermediate-depth seismicity in varied subduction zones. Research methods include tomographic imaging, absolute and double difference relocation of earthquakes. She also works on source property inversions and ground motion calculations.
Zhao Zhu
Zhao Zhu is a 2nd-year Graduate Student interested in the synergies between data science and seismology. Current projects include studying lithospheric drips with seismic anisotropy and the auto-picking of seismic arrivals employing convolutional neural networks.
Hanlin Liu
Hanlin is a visiting student from the Institute of Geophysics, China Earthquake Administration. He is applying our attenuation imaging techniques to data from NE China and southern Mongolia.
Ozan Karayazi
Ozan is a master's student funded on a scholarship from the Turkish government. He will be looking at teleseismic attenuation in Alaska using data from the EarthScope transportable array and other deployments.
Rebeca Pereira
Rebeca has been admitted to our PhD program. She will be exploring the relationship between seismic attenuation (as an indicator of lithospheric strength) and intracontinental seismicity.
