Daniela Porat and Patricia Callahan

Daniela Porat is a reporting fellow. She covers consumer product safety. Prior to joining ProPublica, Porat worked as a reporter for Investigative Post in Buffalo, New York, where she exposed wrongdoing in the local police department. Her reporting led to significant reforms within the department and was twice recognized by the New York State Associated Press Association. In addition to an investigation that documented the stop-and-frisk tactics of two police units, she published a series that exposed how the department’s lax training standards contributed to the fatal drowning of a dive-team officer. As a member of the computer-assisted reporting team at The New York Times, Porat documented over 300 shootings for a report on gun violence across the United States. Her reporting has also been published by VICE News and the Miami Herald. She graduated with honors from the Columbia Journalism School and earned a B.A. in art history and political science from McGill University. Patricia Callahan is a senior reporter covering business. Callahan previously worked at the Chicago Tribune, where she was on the investigative team since 2004. There, she launched “Hidden Hazards,” a series that showed federal safety regulators were repeatedly failing to protect children from dangerous products. This work prompted the recall of more than 1 million baby products, spurred Congress to pass the largest overhaul of consumer product safety laws in a generation, and won the 2008 Pulitzer Prize for investigative reporting. In 2012, Callahan and colleagues showed how harmful chemicals used as flame retardants on furniture were migrating into people’s bodies while providing no meaningful protection from fires. The work led to the repeal of a rule responsible for the use of these chemicals; it also won the Goldsmith prize and was a finalist for the 2013 Pulitzer for investigative reporting. Most recently, Callahan and a colleague were 2017 Pulitzer finalists for a series exposing how Illinois officials steered low-income adults with developmental and intellectual disabilities into substandard privately run group homes, then hid harm and even deaths. Before the Tribune, Callahan worked at the Wall Street Journal, covering the food, pharmaceuticals and publishing industries. There, she revealed how newspaper publishers — including the Journal’s parent company — financially abandoned children injured or killed on their newspaper delivery routes. She came to the Journal from the Denver Post, where she was part of the team that covered the Columbine High School shootings. Trish graduated from Northwestern University’s Medill School of Journalism and was a Henry Luce Scholar in Bangkok.
