Federal charges accusing an assistant professor at Yale University School of Medicine and a Kentucky biomedical researcher of violating U.S. trade sanctions against Iran were dismissed after their co-defendant was swapped for a U.S. student imprisoned in Iran since 2016. 

Yale assistant professor and permanent U.S. resident Mahboobe Ghaedi was prepared to change her not guilty plea when the charges were dismissed, according to the court docket.  Co-defendant Maryam Jazayeri, a naturalized U.S. citizen and Kentucky resident, was scheduled to go to trial in February, said Page Pate, her Atlanta attorney.
