Research interests:

• Carbon biogeochemistry in marginal and estuarine systems with special attention on South China Sea and the Pearl River Estuary.
• Geochemistry of radioactive elements (Plutonium and Thorium) in surface and ground water
• Geochemistry of trace metals in coastal and estuarine environments
  
• Geochemical studies of colloidal material in the transport of trace metals, organic carbon, and radionuclines in surface and ground waters
