Jessikka Aro is an award-winning reporter with Yle, the Finnish Broadcasting Company, specializing in Russia, extremism and information warfare. In 2014 and 2015, she published a series of articles on pro-Kremlin social media trolls and their influence outside of Russia's borders. Due to her investigations, Jessikka became the target of a severe and still ongoing international propaganda and hate speech campaign, which she recounts in Putin's Trolls, sold in 16 territories worldwide.

In 2019, the US State Department awarded Jessikka the International Women of Courage Award, but the award was mysteriously rescinded by the Trump administration, allegedly due to her social media criticism of then President Trump. On December 1, 2020, Jessikka Aro received the International Women's Media Foundation Courage in Journalism Award, presented in partnership with the Washington Post and hosted by CNN's Christiane Amanpour. Jessikka was recognized for her award-winning investigative reporting of Russian information warfare, and she has published three nonfiction titles: Putin's Trolls, Putin's World War, and Putin's USA. Jessikka lives in Helsinki, Finland.
