Kieran Williams, visiting assistant professor of politics, was invited to speak at Harvard on Nov. 18 at a special event to commemorate the 30th anniversary of the 1989 revolution in Czechoslovakia. In September, he was a guest on the Cold War Conversations Podcast, as a witness to the August 1991 attempted coup in Moscow that set in motion the end of the Soviet Union. And, in May, he was cited by a regional court as an authority in a case of a disputed election in the Czech Republic.
