That means political scientist.

Or in this case, Chinese spy.

A retired German political scientist has been charged with spying for China for almost a decade, using the political contacts he developed while working for a think tank, the German federal prosecutor’s office said on Tuesday.

It said the man, identified as Klaus L. according to German reporting custom, had been recruited during a lecture trip to Shanghai in 2010, almost 10 years after joining the think tank, and had regularly passed on information until November 2019, in return for money and trips to China.
