Emory University
Faculty Profile

Yang Liu is an associate professor in Emory University’s Rollins School of Public Health. Liu’s research interests include the application of satellite remote sensing in air pollution exposure modeling and health effects studies at urban to national scales as well as the potential impacts of global climate change on public health.

Yang’s HAQAST work proposes translate research knowledge to our public health partners in two projects.

  1. First, building on our long-standing collaboration with CDC’s Environmental Public Health Tracking Network (Tracking Network), we will conduct a national scale epidemiological study to link age-specific county-level daily counts of emergency department (ED) visits with fused air pollution exposure estimates from satellite observations, model simulations and EPA ground measurements to demonstrate an important application of Tracking’s environmental health surveillance data.
  2. Second, partnering with the Colorado Department of Public Health and Environment (CDPHE), we will conduct a multi-year time-series epidemiological study to evaluate the health impact of air pollution levels elevated by wildfires in Colorado.
