Carol Marbin Miller is deputy investigations editor for the Miami Herald, where she has worked since 2000. Marbin Miller holds degrees from Florida State University and the Columbia University Graduate School of Journalism, and has worked at several Florida newspapers, including the Tampa Bay Times and the Palm Beach Post.
Marbin Miller has won a number of journalism awards, including the Goldsmith Prize, Selden Ring Award, Worth Bingham Award (twice), Associated Press Managing Editors Award, Heywood Broun Award (twice), Eugene S. Pulliam First Amendment Award, the National Headliners' Award, the Online Journalism Awards' Knight Award for Public Service, the Green Eyeshade Award, the Florida Society of News Editors' Gold Medal for Public Service and Paul Hansel Award for Distinguished Achievement in Florida Journalism. A series she co- wrote about assisted living facilities, Neglected to Death, was a Pulitzer Prize finalist for public service in 2012. Another series she co-wrote about Florida's juvenile justice system, Fight Club, was a Pulitzer Prize finalist for investigative reporting in 2018. Fight Club had been produced with the aid of a Center for Health Journalism fellowship.

Writing largely about children and vulnerable adults - and the state agencies that exist to serve them - Marbin Miller's stories often have had significant impact: Her work has led to the passage of 10 state laws, including measures that reformed the state's child welfare system, curbed the use of psychiatric drugs among foster children, overhauled the state's involuntary commitment law, forced the closure of military-style youth boot camps and banned the payment of kickbacks for the referral of psychiatric and substance abuse patients. Marbin Miller's stories also led to the closure of several privately run psychiatric hospitals and assisted living facilities, and the conviction in federal court of 50 so-called patient brokers. One severely disabled teenager was given a new liver after Marbin Miller reported that he had been removed from an organ procurement list because he was in foster care.

Marbin Miller was a 2016 National Fellow and for her Fellowship project reported "Fight Club."
