Peter DeCarlo

Peter DeCarlo is an Associate Professor of Environmental Health and Engineering at Johns Hopkins University. His research focuses on atmospheric air pollution, with applications to ambient air quality, aerosol dynamics, and climate change impacts. He has conducted field measurements globally and engages in policy advocacy on climate and air quality.

• PhD in Atmospheric Science from University of Colorado
• Postdoctoral Fellowship at Paul Scherrer Institute (Switzerland)
• AAAS Science Policy Fellowship in Washington D.C.

Research interests include aerosol source apportionment, indoor-outdoor pollution linkages, and development of low-cost sensors for air quality monitoring. His work integrates advanced instrumentation and policy translation to address environmental health disparities.

Key projects include studies on Louisiana petrochemical corridors, Arctic pollution dynamics, and residential wood burning impacts. Recent findings highlight critical gaps in EPA emissions estimates and alarming ethylene oxide levels in industrialized regions.

Lab activities emphasize bridging science and policy through projects like the Hazardous Air Pollution and Monitoring Assessment (HAP-MAP) initiative. Current research focuses on spatial VOC variations, aerosol chemistry in extreme environments, and community-based participatory risk assessment.
