The primary research interest lies in the development of novel wastewater treatment technologies to recover water, energy, nutrients, and value-added products from wastewater. Previous and current research topics include： 

1. Advanced wastewater treatment for water reuse, including sulfur autotrophic denitrification, denitrification-dependent anaerobic methane oxidation, phosphate adsorption and desalination; 

2. Energy recovery and in-situ utilization, including electricity generation by microbial fuel cells or reverse electrodialysis, microbial desalination cells, and bio-cathode microbial fuel cells for wastewater denitrification; 

3. Nutrient recovery, in particular the adsorption of ammonium, nitrate and phosphate in waste streams using capacitive deionization or ion exchange technologies; 

4. Comprehensive toxicity of water quality, including extracellular electron transport, electroactive biofilm biosensor and early-warning system.
