Research Interests

Dr. Zhu’s research interest is primarily in the field of environmental exposure assessment and aerosol science and technology. Specifically, she is interested in determining the data necessary to fill the knowledge gap in quantitative exposure/risk assessments on vehicular emitted ultrafine particles that have shown higher toxicity than larger particles on a unit mass basis. Her current research focuses on identifying key factors that affect human exposure to ultrafine particles on and near roadways by measuring and modeling their emissions, transport, and transformation in the atmosphere as well as into the in-cabin and indoor environments. These research efforts are supported by two prestigious national awards, the National Science Foundation (NSF)?s Faculty Early Career Development (CAREER) Award and the Walter Rosenblith New Investigator Award from the Health Effects Institute.


Dr. Zhu joined the Environmental Health Sciences Department in UCLA School of Public Health as an Assistant Professor in 2010. Before taking this post, Dr. Zhu has worked as an Assistant Professor in Environmental Engineering Department at Texas A&M University-Kingsville since 2006.
