Dr. Ke Gao received his Bachelor and Master degree in 2010 and 2012, respectively, in Geological Engineering, at the China University of Geosciences (Wuhan). In 2017, he obtained his Ph.D. in Rock Mechanics at the University of Toronto. After that, he spent two years (2017-2019) in the Los Alamos National Laboratory as a Post Doc in Solid Earth Geophysics, and joined in SUSTech in 2019. Dr. Gao’s research mainly focuses on the simulation and investigation of stick-slip characteristics in sheared granular fault using the combined finite-discrete element method, tensor-based stress variability and stress heterogeneity characterization in fractured rock mass, and nonlinear mesoscopic elasticity in geomaterials. Dr. Gao has published nearly 30 papers in various journals and international conferences, and he also acted as reviewers for many Geophysics and Rock Mechanics related journals.
