Research

I am working on the occurrence, behavior, and fate of pharmaceuticals and personal care products (PPCPs) in the environment using combination of chemical and enantiomeric analysis.
My current projects include the occurrence and fate of PPCPs in municipal landfill systems, transport and behavior of azole antifungals in the environment of the Pearl River Delta, and behavior and fate of antibiotics in the environment.
