For nearly 15 years, the Holloway Group has been advancing cutting-edge research and applications related to air quality, energy, transportation, climate, and public health. Each project is designed to meet partner information needs and/or produce original research for publication in top journals. 

We welcome new partnerships where our research methods can advance real-world problems and solutions. 

We are an air quality group based in the Nelson Institute Center for Sustainability and the Global Environment (SAGE) that incorporates professors and students, from a wide range of fields. We have a multidisciplinary team focused on advancing air quality research to inform science and policy.

SAGE is a multidisciplinary research center in the Nelson Institute for Environmental Studies at UW-Madison, with about fifty faculty, scientists, students, and staff examining cutting-edge environmental challenges and solutions. The Nelson Institute is an institute at the University of Wisconsin-Madison that builds partnerships to synergize and sustain excellence in the interdisciplinary research, teaching, and service that make the University of Wisconsin-Madison a world leader in addressing environmental challenges.

The Holloway Group is funded through the University of Wisconsin-Madison by grants, and gifts from a range of organizations, including the Environmental Protection Agency (EPA), NASA, NASA Atmospheric Composition, Global Philanthropy Partnership, Wisconsin Focus on Energy, Wisconsin Department of Transportation (WisDOT), the National Center for Freight Infrastructure, Research, and Education (CFIRE), National Science Foundation (NSF), National Renewable Energy Laboratory (NREL), National Institute of Health (NIH), Wisconsin BioFuels Association, the Wisconsin Corn Growers Association, and the Energy Center of Wisconsin.
