The research focuses on (1) developing state-of-the-art online and offline measurement techniques for atmospheric emerging pollutants, such as micro- and nano-plastic particles, per- and polyfluoroalkyl substances (PFAS), and volatile chemical products (VCPs) ;  (2) the chemical transformation and physical interactions of emerging pollutants in the atmosphere; and (3) the climate impacts of emerging atmospheric pollutants. 

The research focuses on (1) the chemical composition of gases and particles in the atmosphere;  and (2) how chemical kinetics and physicochemical properties jointly impact secondary organic aerosol (SOA) formation and transformation.

This collaborational research focuses on chemical composition and how certain physicochemical properties of aerosols affect cloud condensation and ice nucleation processes. Our experimental results can also be combined with field measurement data and can be used to improve regional and global scale climate models. 

This research examines fundamental properties of aerosols and nanoparticles (such as phase state, phase transitions, and mixing state) using advanced physical chemistry and analytical chemistry techniques. The results obtained from this study will improve knowledge in atmospheric science, chemistry, and material sciences.
