The complaint notes Petrova’s boss at Harvard is Dr. Leonid Peshkin. Peshkin asked Petrova to bring “histological samples of frog embryos” from his scientific collaborators at the Institut Curie Centre de Recherche in France back to Harvard so that their lab could continue processing and analyzing data from them.

Harvard Medical School researcher Kseniia Petrova is detained at a United States Immigration and Customs Enforcement facility in Louisiana after her research visa was revoked last month for inadvertently failing to properly declare frog embryos she brought into the country.
