I cover health and the environment and the agencies that govern them, including the Environmental Protection Agency.

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.

Industry-Backed Legislation Would Bar the Use of Science Behind Hundreds of Environmental Protections

Two bills in Congress would prohibit the Environmental Protection Agency from using hundreds of chemical assessments completed by its IRIS program in environmental regulations or enforcement.

A Study of Mint Plants. A Device to Stop Bleeding. This Is the Scientific Research Ted Cruz Calls “Woke.”

The senator flagged thousands of National Science Foundation grants for using words like “female” and “diversify.” A ProPublica analysis found numerous examples of projects caught up in his crude method for identifying research he calls “woke.”

The Courts Blocked Trump’s Federal Funding Freeze. Agencies Are Withholding Money Anyway.

Agencies continue to suspend funding, despite multiple court orders blocking the federal freeze. Experts say the Trump administration’s actions set the stage for challenges to Congress’ authority — and the limits of the presidency.

“We Feel Terrorized”: What EPA Employees Say About the Decision to Stay or Go Under Trump
