Jianyu Huang was arraigned Tuesday in U.S. District Court in Albuquerque. The Albuquerque Journal reports Huang faces five counts of federal program fraud and one count of false statements.
Authorities say he passed off nanotechnology research that belongs to the U.S. as his own. They say he went online to share the data with state-run schools in China.
Huang is also accused of lying about taking a lab-owned laptop computer there.
Sandia Lab says Huang was fired in April for violating procedures and he never had access to classified national security information.
A message left Wednesday for Huang’s public defender, Brian Pori, was not immediately returned.
