We're dedicated to developing and implementing effective strategies to bring children’s environmental health research to the community, policy making and healthcare.

The Philadelphia Regional Center for Children’s Environmental Health strives to improve the health and wellness of children across the country, by first starting in our own backyard: Philadelphia and the surrounding region.

The children in our area face many environmental threats and health problems– asthma, lead poisoning, air pollution and toxic chemicals. Together, our partners and member researchers work to implement real world solutions and interventions in Philadelphia to serve as a model for success elsewhere.

The Center was founded in December 2021 at the University of Pennsylvania and the Children’s Hospital of Philadelphia, and our membership includes researchers from regional institutions and universities.

What We Do

Philly Proud

It’s our home, and our favorite place in the world. That’s why we are committed to helping our region’s children and solving the environmental health problems that affect our communities, particularly our most vulnerable groups. Meet our community partners.

Support Environmental Health Researchers

Our members include researchers from universities and institutions who focus on the science behind children’s environmental health. Their work is the foundation for our programming, therefore, we provide resources to help them succeed. This includes training, grant writing support, community engagement, networking and collaboration. Meet our members.

Pilot Projects

We provide funding opportunities to members and partners to develop new children’s environmental health resources, programs and research that can be piloted directly in the Philadelphia region. Explore our Pilot Project Funding.


The Center serves as a focal point for communicating children’s environmental health research to the public, government officials and community advocates. Our website, social media, e-newsletter and marketing materials convey the latest scientific information.

Build Innovative Programming

Using the latest research, our team works with partners to launch translational and intervention programming for families. See our list of Programs.

We are part of a national network of Children’s Environmental Health Research and Translation Centers, including:
