Research Area

Atmospheric reactive nitrogen species are major contributors to regional air pollution. Meanwhile, atmospheric deposition of reactive nitrogen serves as a significant pathway of N nutrient input to ecosystems. My work focus on exploring the sources, processes, and sinks of atmospheric inorganic and organic nitrogen species to help evaluate the diverse environmental and health effects of reactive nitrogen.

Research Interests

• Nitrogenous aerosols
• Organic nitrogen
• Atmospheric nitrogen deposition
• Analytical method development for atmospheric applications
