Maddy Varner

Investigative Data Journalist

Maddy Varner was an investigative data journalist for The Markup. She left in May 2023.

Maddy extracts datasets from public documents and databases to help build a more concrete understanding of how organizations use technology to predict and affect behavior—and the problems in those assumptions.

Before The Markup, she was a researcher at ProPublica, where she was on a team that won a Loeb Award for Beat Reporting in 2017 for “Monetizing Hate,” a series of stories that examined Facebook’s ad practices.
