Hao Guo, Associate Professor and Senior Research Scientist in Geophysics and Seismology, member of the Tectonophysics Committee of the Seismological Society of China. He received his Ph.D. in Geophysics from the University of Science and Technology of China in 2019, including one year of joint training at the Woods Hole Oceanographic Institution in the United States. From September 2019 to June 2023, he conducted postdoctoral research at the University of Wisconsin–Madison, where he served as a Research Scientist II from July 2023 to January 2026. He joined Nanjing University in February 2026. He has published more than 20 scientific papers, including 11 as first or corresponding author, in journals such as Nature Geoscience, EPSL, GRL, JGR-SE, GJI, and SRL.

His primary research focuses on multi-scale imaging of Earth’s interior structure and inversion of earthquake source parameters. Specific research directions include:

(1) Development of advanced seismological algorithms and software for earthquake location, seismic tomography, and source parameter inversion (e.g., stress drop), aiming to more accurately resolve subsurface physical state, mechanical properties, and geological and geodynamic processes across different spatial scales. He has developed several algorithms and software packages, including triple-difference seismic location (hypoTD), triple-difference seismic tomography (tomoTD), Vp/Vs consistency-constrained double-difference seismic tomography (tomoDDMC), double-difference seismic attenuation tomography (tomoDDQ), and joint spectral ratio inversion method (SpecRat).

(2) High-resolution imaging of subduction zones, oceanic and continental transform faults, and intraplate faults, to investigate how spatiotemporal variations in physical and rheological properties control fault slip behaviors (e.g., earthquakes, tectonic tremor, slow slip, and aseismic creep) and earthquake rupture processes, with implications for seismic hazard assessment.

(3) Microseismic monitoring and 4-D seismic imaging, aiming to detect spatiotemporal changes in rock physical properties within subsurface energy systems (e.g., geothermal reservoirs) and understand mechanisms of induced seismicity, supporting safe and efficient development of subsurface energy resources.

Undergraduate and graduate students, postdoctoral researchers, research staff, visiting students, and visiting scholars who are interested in the above or related research areas are welcome to join the group.

Postdoctoral Recruitment:
The group is currently recruiting two postdoctoral researchers or research staff. Research directions are flexible, and the compensation package is competitive in China. The positions remain open until filled.
