RESEARCH INTERESTS:

His major research interests include aerosol chemistry and air pollution.  His current research interest focuses on gas – particle interactions, in particular, the thermodynamics and hygroscopic properties of atmospheric aerosols, as well as heterogeneous reactions related to the formation of secondary air pollutants. His research involves both field studies (e.g. mechanisms of sampling artifacts of semi-volatile species in aerosols, size distributions of ionic (inorganic and organic) species, aerosol acidity) and laboratory experiments using single particle levitation technique. His group is one of the first groups to systematically study the hygroscopic properties of atmospheric water-soluble organic compounds (WSOC) and their effects in affecting the growth of inorganic aerosols. He has also pioneered the use of Raman and fluorescence spectroscopy to relate the hygroscopic properties of supersaturated droplets of electrolytes to their structural properties.  Together with Dr. Ming Fang (Institute for Environment and Sustainable Development, HKUST), he co-developed the Mobile Air monitoring Platform (MAP), a vehicle equipped with the state-of-the-art equipment and instruments to monitor air pollution on the road in a real-time, in situ mode, in contrast to the conventional stationary techniques.
