His research is mainly focused on atmospheric radical chemistry, formation mechanisms of the regional air pollution in Chinese Megacities (Pearl River Delta) and recently also worked on several issues on Climate Change. He is one of the leading scientists to steering the continuous development of the atmospheric chemistry discipline in China. For example, he is Vice-Chair of Steering Committee of University teaching of Ministry of education for environmental science and engineering, Co-Chair of the 6th/7th Discipline Appraisal Group for Environmental Science and Engineering of The State Council Academic Degrees Committee; he is also the head of "Blue Sky Science and Technology Engineering Key Projects" of Ministry of Science and Technology and chair of the steering committee for the state major development program "Formation mechanism of the Air pollution and controlling technology".

He conducted continuous research on air pollution processes and control strategy focused on the Pearl River Delta region in the framework of State Basic Research Development Program (973) and Hi-tech development program (863) sponsored by Chinese Ministry Of Science and Technology for more than 20 yrs. He established the Program of Regional Integrated Experiments on Air Quality over Pearl River Delta (PRIDE-PRD), of which a regional 3-dimensional observation platform was set up and comprehenisive field campaigns with international teams from Germany, Japan and United States, etc in 2004, 2006, 2008, 2010 and 2014 were carried out. Within these field experiments, a strategy of data analysis, namely “closure study”, is developed. He had applied the “closure study” strategy for the exploration of the aerosol optical properties and also the budget analysis of HOx radicals. Later on, the “closure study” strategy is used to organize ambient measurement super site which can characterize the status of the secondary air pollutions and elucidate the formation mechanisms. He initiated a “Chinese Alliance of Air Pollution Monitoring Supersites” to promote the domestic collaboration on the study of the air pollution processes including instrument development, data quality assurance and control, data analysis, model development and intercomparison, etc. At the moment, 14 major atmospheric institutes in China are member of this Alliance.

He discovered the important roles of the secondary aerosols and Black Carbon to haze formations as well as sulfate and quantified how long-distance transport affects air quality of PRD. In collaboration with Forschugszentrum Juelich, a new missing OH regeneration mechanism in VOC rich atmospheres was identified and then a parameterized OH model was proposed which confirmed that the new mechanism is a general mechanism which exists in high VOC atmosphere worldwide. In addition to the enhanced OH regeneration, high gaseous HONO is a another significant source of OH radicals in PRD. The photocatalytic of NOx on particle surfaces and soil emissions were found to be important sources of HONO.

Moreover, he also contributed a lot on the air pollution mitigation strategy in Pearl River Delta. He diagnosed that both the PM2.5 and O3 pollution to be a regional problem. A regional monitoring network and forecast system was established and routinely available due to he and his co-workers in PRD. Since then, both primary and secondary pollutions were well characterized which demonstrated that the NO2, PM2.5 and O3 pollution were the most serious problems. Supported by the above scientific studies, the formation mechanisms and source appointments of the regional air pollution complex were elucidated and the pollution mitigation strategy was formulated accordingly. A decision-making mechanism including the interaction among scientists, citizens, and governors was finally developed for the regional air quality management. Due to these activities, the air quality (e.g. SO2, NO2, PM10 and PM2.5) in PRD was improved significantly in recently years. When he started his work on PRD in 1990s, PRD was the most serious air pollution place all over China. After more than two decades of the effort from him and his co-workers, PRD is expected to achieve the Pioneer PM2.5 Compliance in China.

He published 160 SCI papers, 2 papers on Science and Nature Geoscience as corresponding author, 1 paper on Science as co-author. He also organized 2 special issues on Atmos. Environ. and Atmos. Chem. Phys. respectively and honored with second prize of state scientific and technological advance.
