Bio

Songqiao “Shawn” Wei is a seismologist with broad interests in Earth's mantle structures, particularly those associated with subduction zones. His recent work has been focused on imaging seismic structures of the Tonga-Lau subduction system, intermediate-depth seismicity in Tonga, and the mantle transition zone. One of his major interests in methodology is seismic attenuation. Meanwhile, he uses various seismic/geophysical techniques to study mantle discontinuities, subduction zones, and melt/volatiles in the mantle. He likes to collect fresh data from temporary seismic deployment (fun field work!), though he also works on global dataset.

Shawn received degrees from Washington University in St. Louis (Ph.D. 2016, M.A. 2012) and Peking University (M.S. 2010, B.S. 2007). He previously worked at Scripps Institution of Oceanography, UC San Diego as a Green Scholar Postdoctoral Fellow from 2016 to 2017.
