Air Quality Monitoring for Citizen Science

May 22, 2015

Expert: Ron Williams

Air quality has a significant impact on our health. With new, low-cost sensor technologies and apps, everyday citizens can monitor air pollution on-the-go where they live, work, and play—providing valuable information for individuals and communities, as well as troves of data for scientific research. But how accurate and appropriate are these technologies to meet the goals of the community groups? This podcast explores the potential and limitations of next-generation air quality monitors and offers strategies for citizen scientists as they get started.


Ron Williams

Ron Williams is an Air Climate and Energy (ACE) Task Leader with the U.S. Environmental Protection Agency’s National Exposure Research Laboratory. His research focus has been upon human exposures to complex environmental mixtures. These efforts have resulted in approximately 130 peer review journal articles and hundreds of presentations at national and international conferences. He is a recognized expert in the area of human exposure monitoring and has been responsible for designing, executing, and summarizing some of the U.S. EPA’s largest human observational panel studies. His current research focuses on evaluating air quality sensors and development of novel monitoring systems for community-based research. He is continuing to develop and lead multi-pollutant human exposure measurement panel studies involving particulate matter, pollutant gases and select air toxics.
