Seismology
Main interests include structure seismology and seismic methods. Of particular interests are structures of the deep interior of the earth (core and lowermost mantle) and crust and lithosphere of China and east Asia. Seismology is fundamentally an observational science (including broadband seismographs, array observations, distributed optical fibers, and so on). Professor Song's research group seeks innovative methods to extract information from high-quality fine signals or large amounts of seismic data.
Methods involve understanding wiggles of seismograms (seismic data analyses, synthetic seismograms, waveform modeling) or processing of large quantity of data (tomographic inversions, joint inversions, noise interferometry, machine learning). Seismic data used include seismic body waves, surface waves, coda, and noise.

Physics of Earth’s Interior
Physics of the Earth's Interior aims at understanding the inner workings of the Earth: its internal structure, composition, dynamics, and evolution from the lithosphere to the Earth’s core. It is one of the core and most active research areas in solid earth geophysics with global impacts. Prof. Song mainly interests in structure and dynamics of the Earth’s interior, especially on the core and the lowermost mantle as well as structure and tectonics of China and East Asia. Studies rely mainly on seismological and other geophysical observations and methods.
Using seismic waves, Prof. Xiaodong Song and Paul Richard’s groups found (Song and Richards 1996 Nature) and confirmed (Zhang-Song et al. 2005 Science) evidence for the super-rotation of the Earth’s inner core.
Lithosphere structure and continental dynamics
We live on continents. As the remnants of the earth's material cycle, continental crust and lithosphere are geologically diverse and complex. Classical plate tectonics cannot explain the continental deformation and evolution well.
Professor Song's main interests are in continental structure, deformation, and dynamics, including the Qinghai-Tibet Plateau, the Taiwan Orogenic Belt, the lithosphere structure and regional tectonics of East and South Asia, and hazards and forecast.
Research methods mainly rely on seismic wave data analysis, forward modeling and tomography. The main research topics include seismic body wave imaging, seismic noise surface wave imaging, receiver function, joint inversion, and others.
Prof. Song and student Jiangtao Li found that the tearing structure of the Indian mantle lithosphere under southern Tibet, which could a unified mechanisms for some of the mysterious phenomena in the southern Tibet (surface rifting, volcanism in the high Tibetan plateau, segmented crustal deformation, intermediate-depth earthquakes, and clustered seismicity) (Li and Song 2018 PNAS).
Time-dependent geophysics
The development in the past decades has allowed us not only to observe the earth in a three-dimensional also in a four-dimensional way: how the earth medium changes over time. Professor Song's research group uses repeated earthquake and noise interferometry techniques to study the temporal and spatial changes of the crust related to tectonic activities (such as earthquakes). This research is of great significance to earthquake forcast. Repetitive earthquakes are also an excellent tool for studying the rotation and dynamics of the inner core.
Professor Song and student Xu Zhen used the noise coherence method to discover the changes in the crustal medium caused by the Sumatra earthquake (Xu and Song 2018 PNAS).

Seismology/Geophysics Postdoc Fellowships at Peking University
https://postdocs.pku.edu.cn/tzgg/8a7f55bb4ed24cc88dec63ee67680d06.htm
We invite motivated outstanding candidates to apply for the Boya Postdoctoral Fellowships at the School of Earth and Space Sciences at Peking University (PKU) or national postdoc fellowships. Applicants with an interest in seismology or interdisciplinary interests are particularly encouraged to apply.
The fellowship is for a period of 2 years, with a base salary of 200K RMB/year (exchange rates 7-8 RMB/Euro and 6-7 RMB/US$), a housing subsidy of 60K RMB/year, and benefits that include medical and social insurance (in amount of around 91K RMB/year).
Additional compensations will be considered that are commensurate with experience. Accompanying children may enter the kindergarten, primary/secondary school of PKU.
Applicants below the age of 35 with PhDs within the last 3 years are eligible to apply. Applicants from well-known universities/programs are particularly encouraged to apply.
While the fellowship is a personal fellowship to the candidate and therefore allows one to follow own research interests, we are particularly interested in the following areas.
n High-resolution imaging of earth structure and regional tectonics (esp. on east Asia)
n Deep earth structure and dynamics
n Fault zone fine structure and earthquake source processes and physics
n Applications of new techniques, e.g., machine learning, DAS, array processing, joint inversions..
Successful applicants are to work primarily with Prof. Xiaodong Song and are encouraged to collaborate with other PKU faculty members (e.g., Profs. Han Yue and Li Zhao) and with the SinoProbe Lab of the Ministry of Natural Resources (Prof. Shuwen Dong).
The positions remain open until filled (for Fall or Spring). The next deadline for the Fall is mid-October, 2022. Candidates are encouraged to contact us early. Please contact Ms. Diana Wu at lywu@pku.edu.cn for general information and to submit preliminary application materials including a CV and a short statement of research interests. For discussion of research projects, contact Prof. Xiaodong Song (xdsong@pku.edu.cn).
