Ohio State University immunologist is latest to be swept up in probe into undisclosed foreign funding

The US Justice Department has charged yet another professor at an American university with committing research grant fraud to benefit China. Ohio State University’s Song Guo Zheng used more than $4 million (£3.2 million) in grant money from the US National Institutes of Health (NIH) to develop rheumatology and immunology expertise for the Chinese government, according to a criminal complaint unsealed following his 9 July detention hearing.
