I cover the federal government and related national and international issues.

Have a Tip for a Story?

I’m interested in tips about records across federal agencies. I take confidentiality seriously and welcome ideas via secure email, Signal or postal mail.

What I Cover

I’ve contributed to investigations on a range of topics, including the Centers for Disease Control and Prevention’s hobbled response to the COVID-19 pandemic, the rise and ramifications of Chinese transnational repression and organized crime, and the federal judiciary’s repeated failures to provide ethical oversight for its judges.

My Background

My collaborations with colleagues at ProPublica have received numerous honors, including the 2024 Pulitzer Prize for Public Service, a Selden Ring Award, an Investigative Reporters and Editors Award and medal, and recognition as a finalist for the 2021 Pulitzer Prize for Public Service.

Prior to joining ProPublica, I was an editor at Future Tense, the deputy director of the New America Fellows program and a reporter at the New England Center for Investigative Reporting. I was also once an intern at ProPublica.

Formaldehyde Causes More Cancer Than Any Other Toxic Air Pollutant. Little Is Being Done to Curb the Risk.
