Dr Yujiang Xie is a Research Fellow in Computational Seismology working with Prof. Catherine Rychert and Prof. Nicholas Harmon within Ocean and Earth Science, National Oceanography Centre Southampton (NOCS) at the University of Southampton, UK.


2017: PhD Earth System Science (cum laude), University of Hamburg, Germany

2013: MSc Geological Engineering (excellent), Lanzhou University, China

2010: Bsc Geological Engineering (excellent), China University of Mining and Technology, Beijing

Research Interests: Geophysics, Seismology, Mechanics, Mathematics, and Computer Science; Specializing in wave equations and simulations, numerical methods (e.g., FEM, SEM, and FD), partial differential equations (PDEs), inverse theory, optimization algorithms, machine learning, and software development; One application is the full waveform inversion or adjoint state tomography for exploration, regional, and global seismology.

Early research includes optimization algorithms, parametric search of wavefront properties, interpolation of five-dimensional data, ray theory, seismic imaging with stack and/or migration methods, and travel time tomography.
