Federal prosecutors in New York had charged Zhu and two other NYU researchers, also Chinese nationals, with taking bribes from
United in exchange for inside information about their federally funded
research on medical imaging, particularly MRI technology.
Charges were dropped against one of the other defendants, and the third was
believed to have fled to China before being charged two years ago.
Zhu was originally charged with taking payments and other financial favors
from United in 2011 shortly after receiving a $4 million NIH grant for
Prosecutors said at the time of the charges that the three were caught after NYU became suspicious and filmed them in the
lab in contact with United Imaging Healthcare in Shanghai.
