Karl-Henrik Grinnemo was worried. The doctor and clinical researcher at the Karolinska Institute was working with a high-profile surgeon who was performing a potentially life-saving procedure on patients, but Grinnemo saw that the patients weren’t doing very well. So in 2013, Grinnemo and three other doctors raised concerns about the work of Paolo Macchiarini. The surgeon initially fought back, and accused Grinnemo of misconduct. KI sided with the star surgeon, and found Grinnemo guilty of “carelessness” in a grant application to the Swedish Research Council, including plagiarism. Readers should by now know how the story ends – Macchiarini’s work has since been largely discredited. Recently, to clear his name, Grinnemo asked authorities to take a second look at his case – and he has been exonerated. We talked to him about the last few tumultuous years.
