A 30-year-old Harvard researcher from Russia has been held for more than a month at a private detention center in Louisiana where federal immigration officers are sending a growing number of international students with lives here suddenly in jeopardy.

Kseniia Petrova was returning from a two-week vacation in France, where she went to see a famed classical pianist perform, when she was detained at Logan International Airport on Feb. 16, Leonid Peshkin, a principal research scientist at Harvard, said in a phone interview.

The woman is being held in a Louisiana detention facility while waiting for her next hearing. The post A Harvard scientist from Russia has been detained by ICE since February for failing to declare frog embryos appeared first on Boston.
