1. Advanced Numerical Analysis

2. Mechanics of Granular Materials

3. Dynamics of Sediment-fluid Flows

4. Principles and Numerical Analysis of Geotechnical Engineering

We study the flow and transport of granular materials (soil, sediment, ice) and other related phenomena in nature and engineering using a multiscale approach (from particle to continuum scales) combining experiments, simulations, and theory. The overarching theme is “Multi-Scale Mechanics for Earth and its Environment”, in line with the UN’s and China’s sustainable development goals. Our ultimate goal is to promote scientific solutions for geohazard mitigation and sediment management in fluvial and marine environments.
