About Me
I am an Engineer at the Institute of Mountain Hazards and Environment, Chinese Academy of Sciences. My research focuses on the dynamics of debris flows, landslide-dam formation and failure, and the multi-process evolution of geohazard chains. I am particularly interested in how fluid–particle interactions, rheological transitions, and topographic controls influence the mobility and deposition of rapid mass flows. My work combines physical experiments, two-phase continuum modeling, numerical simulation, and field-oriented hazard analysis. I have contributed to the development of debris-flow models incorporating visco-inertial rheology and to experimental studies on landslide-dam formation and breaching processes. My broader goal is to improve the physical understanding and predictive capability of geohazard simulation for hazard mitigation and resilient mountain infrastructure.

Research Interests
-
Debris-Flow Dynamics and Rheology
I investigate the mechanics of debris flows using two-phase continuum frameworks, with emphasis on visco-inertial rheology, phase interactions, and mobility enhancement in saturated granular-fluid mixtures. -
Landslide-Dam Formation and Breach Processes
My research explores how landslide mobility and river-flow conditions jointly control river blockage, dam geometry, and breach evolution through experiments and process-based analysis. -
Geohazard Chain Simulation and Hazard Assessment
I work on numerical simulation of cascading geohazard processes in mountainous regions, aiming to improve hazard prediction, scenario analysis, and risk-informed mitigation planning.
Research Highlights
- Developed a two-phase debris-flow model incorporating visco-inertial rheology to better capture enhanced mobility and phase separation in debris flows.
- Contributed to experimental and numerical studies on landslide-dam formation, river blockage, and overtopping/breach evolution.
- Participated in geohazard-chain simulation research with applications to mountain hazard mitigation and infrastructure safety.
