Ryan Gabrielson is a reporter for ProPublica covering health care.

Previously, his reporting on the justice system exposed major flaws in forensic science evidence long relied on in the criminal courts, the U.S. Supreme Court’s factual errors and deadly conditions inside local jails.

In 2009, while a reporter at the East Valley Tribune in Mesa, Arizona, he and Tribune colleague Paul Giblin won a Pulitzer Prize for a series that exposed how immigration enforcement by the Maricopa County Sheriff's Office undermined investigations and emergency response. His stories for the Center for Investigative Reporting on violent crimes at California’s board-and-care institutions for the developmentally disabled were a finalist for the Pulitzer Prize for public service in 2013.

Gabrielson's work has received numerous national honors, including two George Polk Awards, a Livingston Award for national reporting, the Al Nakkula Award for Police Reporting and a pair of Sigma Delta Chi Awards. He was a 2009-2010 investigative reporting fellow at UC Berkeley. A Phoenix native, Gabrielson studied journalism at the University of Arizona.
