In July, an Iowa District Court sentenced biomedical researcher Dong-Pyou Han, formerly of Iowa State University, to 57 months in prison and $7.2 million in restitution for scientific misconduct. The unusual sentence sparked debate among scientists on whether the punishments fit the crime.

Han altered rabbit blood samples to artificially boost HIV vaccine test results, leading to millions in grant money. A 2013 investigation by the U.S. Office of Research Integrity uncovered his misdeeds. The agency imposed a three-year research ban on Iowa State, which returned $500,000 in grant money. Criminal charges followed in June 2014 after the case gained widespread attention.

Extreme fraud like Han’s is rare, but subsequent legal prosecution is almost unheard of, says Daniele Fanelli, a meta-researcher at Stanford University. Fanelli believes similar prosecutions may follow. “This might have serious consequences on scientific progress,” he says, both positive and negative. “If you turn a judgment about scientific truthfulness into a legalistic manner, then scientists may get away with fraud thanks to having a good lawyer.”
