Ellis Simani is a data reporter at ProPublica.

His recent work has focused on the stock trading of the wealthiest Americans. In “The Inside Edge,” he and his colleagues revealed several investment advantages that enable top executives and other well-connected investors to trade stock with remarkable timing.

Prior to that, he worked with a team of reporters on “The Secret IRS Files,” which investigated systemic inequities in the U.S. tax system that allow the ultrawealthy to avoid paying federal income taxes. The series won a number of awards, including the Selden Ring and the Barlett & Steele Award.

He’s also covered issues related to housing and debt for ProPublica, with a particular focus on evictions. Before joining ProPublica, he worked on the Los Angeles Times’ data visualization desk.
