Three Chinese nationals affiliated with a University of Michigan laboratory have been charged by federal prosecutors for allegedly conspiring to smuggle biological materials disguised as routine research goods into the United States. The individuals, who entered the country under J-1 visas and worked at the institution’s molecular biology lab, face federal counts including conspiracy to import prohibited material and making false statements to U.S. Customs officials.
According to the criminal complaint, shipments sent from China in 2024 and 2025 contained petri dishes and other biological samples labeled as innocuous goods, when investigators say they actually involved roundworms and plasmids used for genetic modification. The materials were directed to apartments and lab addresses in the U.S. tied to the named defendants.
One of the researchers attempted to depart the U.S. in October, booking a flight from JFK International Airport and was intercepted by Customs and Border Protection agents following intelligence leads. The University of Michigan responded by launching an internal probe that resulted in the termination of the accused scholars for failing to cooperate with investigators.
Law-enforcement agencies flagged the case as part of a broader concern about foreign national access to U.S. research facilities and the risks posed when biological materials are moved without oversight. Immigration and research-security experts are now reviewing screening and oversight protocols at universities to prevent similar incidents in the future.
