Dr. Yifang Zhu serves as professor in the Department of Environmental Health Sciences. Her research interest is primarily in the field of air pollution, environmental exposure assessment, and aerosol science and technology. Specifically, she is interested in quantitative exposure/risk assessments on ultrafine particles from various indoor and outdoor sources. Her current research focuses on measuring and modeling ultrafine particle emissions, transport, and transformation on and near roadways as well as in various indoor environments.  Her scholarship and creativity has been recognized by several national awards, including the Walter A. Rosenblith New Investigator Award from the Health Effects Institute in 2007, the Faculty Early Career Development (CAREER) Award from the National Science Foundation in 2009, and the Haagen-Smit Prize from Atmosphere Environment in 2011.Dr. Zhu was appointed to California Air Resource Board (CARB)’s Research Screening Committee in January 2014.
