His research focuses on elucidating the HOx radical chemistry for the polluted urban areas. So far, three major progesses have been made on this topic: (1) they successfully performed HOx radical measurements in China for the first time; (2) they have setup a comprehensive framework to explore the radical budgets in a systematical way following the concept of “closure study” and they discovered a critical and so far unrecognized OH regeneration channel in VOCs rich environments; (3) they have synthesized several observational based methods to characterize the photochemical ozone formation regimes with much better accuracy and they obtained a preliminary picture of its temporal and spatial patterns. His research interests have now also been gradually extended to the HOx radical chemistry over forested areas, nighttime radical chemistry, secondary organic aerosol formations, kinetics studies for the chemical mechanism development and the flight measurements of tropospheric trace gas compounds, etc.
