Research Interest

Dr. Zhu's research interests include the analysis of temporal and spatial trends of traffic related air pollutants, the design and operation of size-selective particle detection instrumentation, the evaluation of ultrafine particle exposures, and development and use of various statistical and air quality modeling tools to predict air pollutant including ultrafine particle concentrations in urban environment.

Dr. Zhu was the lead author of two seminal studies evaluating how pollutant concentrations vary with distance from the road. Her research team studied two southern California freeways, the 405 freeway (dominated by gasoline-powered vehicles) and the 710 freeway (with a greater mix of heavy-duty diesel vehicles), in both summer and winter. The field study findings, published as two articles (in Atmospheric Environment and the Journal of the Air & Waste Management Association), show how carbon monoxide (CO), black carbon, and ultrafine particulate matter (PM) number concentrations vary with distance from heavily traveled freeways.
