The head of Harvard University's chemistry department has been found guilty of lying to US officials about his ties to Chinese research after pocketing millions of dollars from Beijing.
Charles Lieber, 62, flew from Wuhan to Boston with bags filled with up to $100,000 in cash after striking a deal to share his nanoscience expertise with Chinese academics.
He was arrested in January over his involvement in the Thousand Talents Plan - designed by the Chinese Communist Party to recruit high-ranking scientists and researchers in foreign countries to funnel intelligence back to Beijing.
Lieber denied his involvement when questioned by US authorities, including the National Institutes of Health (NIH), which had provided his department with millions of dollars in research funding.
He concealed his income from the Chinese program, including $50,000 per month from the Wuhan University of Technology, up to $158,000 in living expenses and more than $1.5 million in grants.
