Research
Our research focuses on the chemical composition, sources, and evolution of atmospheric aerosol across urban, rural, high-altitude, and marine environments. We integrate field observations and laboratory experiments with online measurements, offline analyses, machine learning, and, where appropriate, atmospheric modelling. Our measurement and analytical methods include online aerosol and gas-phase mass spectrometry, offline ultrahigh-resolution mass spectrometry, optical and hygroscopic measurements, and isotope analysis. This integrated framework enables us to characterize atmospheric aerosol from bulk composition to molecular-level detail and to investigate its secondary formation, atmospheric aging, physicochemical properties, and environmental effects. We further develop and apply data-driven approaches to interpret complex aerosol datasets and predict aerosol properties. Through these efforts, we seek to advance the understanding of aerosol chemistry and impacts on air quality, human health, and climate.
