Serkan Gölge, a 36-year-old physicist and research scientist at the National Aeronautics and Space Administration (NASA) in the US, has been held under solitary confinement in Turkey over coup charges.

Dual citizen of the US and Turkey, Gölge was detained as part of an investigation into the Gülen movement, which the government accuses of organizing a coup attempt on July 15.

“[Mr. Gölge] has not been allowed a visit from US consular representatives, and that he has been subjected to extended periods of solitary confinement, putting him at risk of torture or ill-treatment,” Co-Chairs of the Committee of Concerned Scientists said in a letter to Turkish President Recep Tayyip Erdoğan dated Jan 11, 2017.

In the very aftermath of the July 15 coup attempt, Turkey announced a State of Emergency, under which basic human rights came under jeopardy. More than 120,000 people lost their jobs, over 81,000 were detained and some 40,000 arrested in post-coup government purges.
