Shangping Xu's Research
My primary research interest lies in the protection of water resources and the supply of safe drinking water. Anthropogenic activities have profoundly altered the hydrological cycle and water qualities on local, regional and global scales. My research group aims at improving our understanding of the transport and fate of colloid-sized particles (mineral particles, particulate organic matter, bacteria and protozoa) as well as colloid-bound contaminants in both natural subsurface environments and engineered systems (i.e. drinking water treatment facility). Our current research projects include:
- Steric trapping of colloid-sized particles in physically and chemically heterogeneous porous media.
- Filtration behavior of pathogenic bacteria in both saturated and unsaturated porous media.
- Transport and fate of colloid-bound emerging contaminants on a watershed scale.
- Roles of wetland systems in flood control and water quality improvement.
- Behavior and toxicity of nanoparticles in the environment.
- Innovative techniques for drinking water purification and wastewater treatment.
