I report on the EPA and related agencies that oversee the environment, climate change and science.

Have a Tip for a Story?

I’m interested in talking to people who work at the EPA, NOAA, USGS and similar agencies. Please reach out securely via Signal or email if you have a story idea.

What I Cover

I cover how environmental regulations (or the lack thereof) affect communities, human health and the natural world.

My Background

I joined ProPublica in 2017 to cover environmental health and the fossil fuel industry. I’ve written about false solutions related to plastic recycling, carbon credits and biodiversity offsets. I’ve chronicled conflicts of interest in scientific research and regulators’ inability to curb major polluters. I’m currently focused on how the Trump administration is changing environmental protections. My reporting has led to regulatory change and has been cited in lawsuits.

Prior to ProPublica, I worked at Inside Climate News, where I was part of the reporting team that revealed Exxon’s shift from conducting global warming research to supporting climate denial. I co-wrote “The Dilbit Disaster,” which won a Pulitzer Prize for national reporting. I have degrees in earth science and science writing from the Massachusetts Institute of Technology.

Air Monitors Alone Won’t Save Communities From Toxic Industrial Air Pollution

When Home Is a Toxic Hot Spot

More than a thousand people talked to ProPublica about living in hot spots for cancer-causing air pollution. Most never got a warning from the EPA. They are rallying neighbors, packing civic meetings and signing petitions for reform.

Veneno en el aire

La EPA permite a los contaminadores que conviertan barrios en “zonas de sacrificio” donde los residentes respiran carcinógenos. ProPublica revela dónde están esos lugares en un mapa, el primero de este tipo, y con análisis de datos.
