Nature: University of Michigan professor resigns amid questions about his research

According to a report in Nature, University of Pennsylvania researcher Uri Simonsohn —whose apparent uncovering of fraud in a prominent Dutch researcher's work made news earlier this year— says he's uncovered "unlikely" data and results in studies published by former U-M faculty Lawrence Sanna.

Nature reports that Sanna resigned in May, but that the reasons for his resignation are unknown.

The editor of the Journal of Experimental Social Psychology told Nature that Sanna recently asked the journal to retract three of his papers, published between 2009 and 2011 when Sanna was a researcher at the University of North Carolina at Chapel Hill. UNC apparently investigated Sanna's research methods, but did not publicly disclose the results of the investigation.
