Stanford President Marc Tessier-Lavigne is resigning due to manipulated research data in several papers, which will be retracted or corrected. An investigation found that Tessier-Lavigne failed to address concerns about his research and fostered an unhealthy lab dynamic. The report concluded that there was no evidence of direct fraud by Tessier-Lavigne, but he did not adequately address issues with his research. The resignation is effective August 31.
