I’m interested in the field of phytoremediation, restoration ecology and wetland biogeochemistry. I am working on the behavior of contaminants in wetland ecosystem, especially in the aspect of how the oxidized rhizosphere affecting metal and nutrients transformation in water-sediment interface.

research activities
