In Northern California, the president of Stanford University is resigning after a review of scientific research papers he authored or co-authored found they contained manipulated data. Marc Tessier-Lavigne, a renowned neuroscientist, will also retract or issue corrections on five papers. Tessier-Lavigne was previously an executive at the biotech company Genentech, where he published a 2009 study on Alzheimer’s which the review found had “multiple problems.” Tessier-Lavigne’s downfall was prompted by investigative reports authored by 18-year-old freshman reporter Theo Baker, a writer for The Stanford Daily newspaper, who dug into rumors in the science world about the falsified data. He spoke to a local ABC News affiliate about the case Wednesday.

Theo Baker: “All told, there are about a dozen papers on which Tessier-Lavigne is a co-author, a named co-author, that seem to have manipulated imagery. For five of those, he was the principal author. And he has now agreed, as a result of this report, that also led to him stepping down, to retract or issue lengthy corrections to all of these very widely cited papers. And that’s something that definitely wouldn’t have happened had our reporting not brought this into the fore and Stanford decided to investigate itself.”

Theo Baker became the first-ever college student to win a George Polk Award for his reporting on the case.
