Healthy Environment and Endocrine Disruptor Strategies
HEEDS is a non-profit coalition of scientists dedicated to improving communication, coordination and collaboration in the field of endocrine disrupting chemicals (EDCs). HEEDS is developed by scientists for scientists. There are no membership fees. HEEDS works to move EDC science forward, increase collaborations across scientific disciplines, communicate results and improve policy and regulations.
We are now accepting applications for the 2026 Lou Guillette Jr. Outstanding Young Investigator Award!
Due Sept. 30, 2026.
Congratulations to our EDC-North Carolina poster award winners!

- Developing an EDC training portal - Share your input
by Sarah Howard on June 23, 2026 at 2:41 pmHEEDS and the Intersectoral Center for Endocrine Disruptor Analysis (ICEDA) are collaborating to create an online training portal on endocrine disrupting chemicals (EDCs). We are gathering input to better understand needs, potential uses, and content priorities. Please help by filling out the survey!
- New online course: EDCs 101
by Sarah Howard on June 22, 2026 at 5:41 pmHEEDS has created an online course on endocrine disrupting chemicals and we are looking for people to try it out. This course is designed to break down how endocrine disrupting chemicals work inside the body and the supporting evidence about how these chemicals change the way we think about health.
HEED The Call
Your donation will help HEEDS provide education and outreach activities, scientific reports and publications, scientific workshops and webinars as well as other activities and programs to reduce exposure to EDCs and improve health. We are a program of Environmental Health Sciences.
