Dr. Ng’s research interest is in aerosol chemistry, air quality, and health effects. Her research focuses on both laboratory experiments and field measurements to understand the formation and evolution of atmospheric nanoparticles (aerosols). This research includes conducting laboratory chamber experiments in which specific compounds of interest can be isolated and studied under simple, well-controlled oxidation environments, allowing for a more detailed and direct characterization of the composition, chemical, and physical properties of aerosols. Dr. Ng is also involved in field measurement campaigns and integrated analysis of multidimensional and multiple worldwide mass spectrometer datasets to investigate the chemistry and life cycles (sources, processes, and fates) of ambient aerosols.
