Gang Chen, 56, a Chinese-born mechanical engineer and nanotechnologist, was charged by federal prosecutors with defrauding the U.S. Department of Energy when seeking grants, hiding his working relationship with the Chinese government, and failing to disclose a foreign bank account on a tax return. Chen is a naturalized U.S. citizen and professor at the Massachusetts Institute of Technology (MIT).

Robert Fisher, the attorney for Chen said that his client “loves the United States and looks forward to vigorously defending these allegations.”

“Since Gang moved to this country over 30 years ago, his life has been the epitome of the American dream. He has dedicated his life to scientific advancement in mechanical engineering,” Fisher said in an email.

Joseph Bonavolonta, the Special Agent in Charge (SAC) of the FBI office in Boston said at a news conference that, “Our investigation found Chen was working with the Chinese communist government in various capacities dating back to 2012 at our country’s expense.”
