Research Interests:

 Why does the fault exist in the crust ? Why is rock deformed rheologically by stress ? Why do the deformation-fracturing phenomenon have a variety of kinds of duality (e.g . Hodge duality) and symmetry properties (e.g., Fractal) ? I study the deformation-fracture theory of the crust including a fault defect field to clear the origin of the duality and symmetry in deformation-fracturing processes
