What I Cover
My beat is health and the environment. Specifically, I cover the Environmental Protection Agency, charting its handling of pesticides, plastic-based fuels and other chemicals. I have reported on EPA whistleblowers who were pressured to downplay the harms posed by new chemicals, as well as on plastic, greenwashing and biosafety.
I have also written extensively about PFAS, a family of industrial pollutants linked to cancer, infertility, developmental harm and immune dysfunction. My reporting has focused on corporate irresponsibility and on the knowledge that PFAS manufacturers 3M and DuPont had of the chemicals’ harms.
My Background
I joined ProPublica in 2022 after seven years as an investigative reporter at The Intercept.
I’ve received numerous local and national awards for my reporting, including being honored by the Society of Environmental Journalists 12 times and by the Newswomen’s Club of New York, which named me its journalist of the year in 2021.

EPA Scientists Said They Were Pressured to Downplay Harms From Chemicals. A Watchdog Found They Were Retaliated Against.

The U.S. Banned Farmers From Using a Brain-Harming Pesticide on Food. Why Has It Slowed a Global Ban?
Chlorpyrifos is so harmful that America banned its use on food. But a top EPA official made it clear that the U.S. was not ready to support similar protections for the rest of the world under a treaty that restricts pollutants that travel the globe.
