Dr. Yu's teaching and research interests focus on air quality and aerosol sciences, with emphasis on characterization of aerosols emitting from combustion sources, and behavior of oxygenated organic compounds in atmospheric particulates, in particular, processes of photooxidation and chemical transformation of dicarboxylic acids. Dr. Yu's research group also strives to better understand impacts of transboundary biomass burning smoke on urban atmospheric environment.
In collaboration with Yong Loo Lin School of Medicine at NUS, Dr. Yu expands her research interests to explore potential health effects of engineered nanomaterials. Dr. Yu also works with a multi-disciplinary team at NUS to examine potential impacts of engineered nanomaterials on environment and biological systems.
