The main focus of my research is in rock mechanics. My current research includes:
Rock mechanics and rock engineering:
The rock mechanics application demands the understanding the complex behavior of rocks and rock masses. My research interests are from laboratory to in-situ testing to the numerical and analytical modelling of rock materials.
Nuclear waste disposal:
The waste in a nuclear repository generates heat for hundreds to thousands of years. The stability, deformation and water flow characteristics of the rock mass is influenced by the introduced thermal pulse. Coupled geomechanical process of the rocks must be understood sufficiently before disposing the nuclear waste. My interest are in the laboratory and field scale experiments, and numerical modelling related to nuclear waste disposal.
Numerical modelling in geomechanics:
When rock-engineering problems are complex, some form of numerical modelling is typically carried out to help in finding a suitable solution. Today, discrete element methods (DEM) are commonly used and offer many advantages over the complex constitutive models used in continuum modelling when simulating intact rock. My interests are in understanding the complex rock behavior using DEM and the application of continuum codes for rock mechanics problems.
Slope stability:
Catastrophic slope failure of natural and man-made slopes requires deeper understanding of geological and physical processes of rock and rock mass. My interest is to improve our understanding of the mechanism involved.
