Research Interests

I am a researcher specializing in computational mechanics (Peridynamics, FEM, FVM, LBM), with particular interests in: 

• Damage and fracture of solids;

• Flow and transport in fractured porous media;

• Personal interests in thermodynamics and fundamentals of continuum mechanics

​

The application background include geomechanics, geoscience, reservoir engineering, geothermal engineering, nuclear waste disposal, coal mining, etc. 

In most of my research, I apply the findings and methodologies to deformable fractured porous media, which is commonly encountered in real-world applications. The primary goal is to achieve a unified formulation for applications grounded in continuum mechanics and thermodynamics. We do not know what beauty is hidden in the world.

Experiences

I obtained my PhD in Geotechnical Engineering (specializing in rock mechanics and computational geomechanics), from the Institute of Rock and Soil Mechanics, Chinese Academy of Sciences, Wuhan, China, supervised by Prof. W Chen, and my BSc degree in Mining Engineering from Shandong University of Science and Technology, Qingdao, China. I am proud of my alma mater. 

​

​I am currently a postdoctoral fellow at The Hong Kong Polytechnic University (PolyU) in Hong Kong SAR, China, in cooperation with Prof. ZY Yin, as a member in GeoInvention group. Prior to joining PolyU, I was a visiting PhD student at Delft University of Technology, the Netherlands, supervised by Prof.dr.ir. C Vuik and Prof. H Hajibeygi, as a member in DARSim group, and later continued my career as a postdoctoral fellow at the CNRS GeoRessources Lab, Nancy, France, funded by the Eurad project under the framework of Horizon2020, in cooperation with Prof. ‪F Golfier. All of these experiences are unforgettable in my life.

A Glimpse into My Research

​​​​I developed my own simulators from scratch using C/C++, Fortran, and Matlab. The numerical methods implemented include: the unstructured (mixed-) finite element method, based on the constrained variational principle, for modeling deformation, crack surface contact, crack growth, and failure in cracked solids; the unstructured finite volume method for simulating fluid flow and transport in 3D fractured porous media; peridynamics for modeling solid fragmentation; and the lattice Boltzmann method for modeling coupled geomechanics-flow in porous media at the mesoscale. I achieved simulations involving 3D multiple intersecting cracks.

 

Here is an introduction of my research, click. 

 

Beyond these primary studies, I have my own personal interests, particularly in some miscellaneous topics related to continuum mechanics and thermodynamics, and their applications in rock mechanics.
