Welcome to the Zhu Research Group at UCLA


Bringing clean air to all in greater Los Angeles, California, the Nation, and the World.


Our team strives to conduct aerosol and air quality research of the highest quality. Our research, both locally and globally, enables policymakers to reduce long-term air pollutant emissions and devise short-term policies to reduce human exposures and protect public health.

Dr. Yifang Zhu

Dr. Yifang Zhu is a professor of Environmental Health Sciences at UCLA Fielding School of Public Health where she also serves as the senior associate dean for academic programs. Her research focuses on measuring and modeling particle emissions, transport, and transformation in both outdoor and indoor environments as well as assessing and mitigating the associated adverse health effects. 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’s Research Screening Committee in January 2014.
