BOSTON — A Harvard University professor charged with hiding his ties to a Chinese-run recruitment program was found guilty on all counts Tuesday.

Charles Lieber, 62, the former chair of Harvard's department of chemistry and chemical biology, had pleaded not guilty to two counts of filing false tax returns, two counts of making false statements, and two counts of failing to file reports for a foreign bank account in China.

The jury deliberated for about two hours and 45 minutes before announcing the verdict following five days of testimony in Boston federal court.
