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 is currently an assistant professor at MSU. He received degrees from Washington University in St. Louis (Ph.D. 2016, M.A. 2012) and Peking University (M.S. 2010, B.S. 2007), and worked at Scripps Institution of Oceanography, UC San Diego as a Green Scholar Postdoctoral Fellow from 2016 to 2017.

Shawn is looking for talented graduate students and postdocs! If you are interested in subduction zone and/or mantle structures, or if you are enthusiastic about field work (on-shore or off-shore), you may want to consider joining this group. Please email Shawn for potential projects. The Graduate Programs page has more academic information for prospective graduate students.
