Research interest 
My researches focus on tropospheric air pollutants (ozone, particulates, and greenhouse gases) and the interactions between air pollutants and meteorology. I use a combination of measurements and state-of-the-art regional and global models to investigate how important species of trace gases/aerosols are emitted, transformed, and transported within our atmosphere.
