ProPublica is pleased to announce that it has won two George Polk Awards this year, in collaboration with our partners NPR and Frontline, for the series "Brain Wars" and "Law & Disorder."

A collaborative project by ProPublica's T. Christian Miller and NPR's Daniel Zwerdling and Susanne Reber, "Brain Wars" found that the U.S. military was failing to diagnose and treat traumatic brain injuries suffered by soldiers. It has been selected for the George Polk Award for Radio Reporting.

ProPublica's A.C. Thompson along with our partners Raney Aronson and Tom Jennings at Frontline and Laura Maggi and Brendan McCarthy at The Times-Picayune won the George Polk Award for Television Reporting for "Law & Disorder," which took an in-depth look at the controversial and often brutal actions taken by the New Orleans Police Department in the aftermath of Hurricane Katrina.

The George Polk Awards are conferred every year to honor special achievement in journalism, particularly investigative and enterprise reporting. ProPublica's Abrahm Lustgarten was among the winners last year for his reporting on the dangers of drilling for natural gas.

Congratulations to all of the winners.
