Learn More About Our Program

Mailman School of Public Health at Columbia University searches for talented, undiscovered voices in environmental health that will become Agents of Change.

​​We’re amplifying the voices of those that haven’t been prioritized in science and academia—people who are already pushing our planet forward in a health-for-all direction. They’re inspiring the next generation of scientists, and they’re capable of so much more.

Mission

Our mission is to empower emerging leaders from backgrounds often neglected in science and academia to reimagine solutions for a healthy-for-all planet.

Vision

Our vision is to foster a new cadre of multifaceted thought leaders who can help create the big changes needed to ensure everyone enjoys a healthy environment by integrating the best available science and technology with the intergenerational knowledge of communities enduring high pollution whose voices haven’t been prioritized in decision-making for unfair reasons.

Goals

  1. Inject new ideas about health and environmental issues by building and strengthening alliances and collaborations with other programs, institutions and media organizations.
  2. Advance the careers and impact of our fellows, helping them become the next generation of thought leaders.
  3. Bring our fellows’ expertise into decision-making spaces.
  4. Make scientific information more accessible to a general audience and those suffering from high pollution levels.

Our institutional home

The program is administered through the Environmental Health Sciences department at Columbia University Mailman School of Public Health.

FORMER Partner

Until 2025, when the newsroom was shut down, the program partnered with Environmental Health News, a publication of Environmental Health Sciences, a nonprofit, nonpartisan organization dedicated to driving policy on environmental health issues.
