PROFILE

Prof. Zheng’s research focuses on developing tools for chemical characterization and measurement of particulate air pollutants especially carbonaceous aerosol to quantify sources and understand their impacts. The primary goal of developing different tools is to improve accuracy of source apportionment of fine particulate matter (PM2.5) and to better understand impacts of air pollutants on human health and climate change. She has collaborated widely with domestic and international scientists. She is interested in interdisciplinary research for improved and integrated methods to study sources of aerosol including receptor modeling with organic and inorganic tracers, source-oriented modeling, and isotope analysis such as 14C. She currently leads a research team at Peking University and her on-going projects include developing online source apportionment of fine PM using single particle mass spectrometry, light absorbing properties and efficiencies of organic carbon in aerosol (brown carbon), changes of aerosol properties from land to sea, and the role of organic aerosol especially secondary organic aerosol during severe haze in megacities of China.
