Rozenfeld Sofya Borisovna

Sofya Rozenfeld — Doctor of Biological Sciences and senior researcher at the Institute of Ecology and Evolution of the Russian Academy of Sciences. She is one of the leading specialists in Arctic waterfowl. She actively opposed a bill that would weaken the ban on the killing of Red Data Book species.

In October 2026, a court found Sofya Rozenfeld guilty of financing the activities of an extremist organisation and sentenced her to 3 years and 6 months' imprisonment in a penal colony.

Rozenfeld was charged over two donations to the Anti-Corruption Foundation (FBK), made in August and September 2021, after the organisation had been designated as 'extremist'. She said that at the time she was on a long-term scientific expedition without access to communications. When the scientist learned that the ban on the Anti-Corruption Foundation had come into force, she cancelled her subscription.
