"Looking forward to welcoming Ambassador Marie Yovanovitch to Ukraine next week! She has been sworn in at the Department of State and will present her credentials to President Poroshenko after she arrives in country," the embassy's press service wrote on Facebook on Friday.

From 2008 to 2011 Yovanovitch was U.S. Ambassador to Armenia, and also served as U.S. Ambassador to Kyrgyzstan from 2005 to 2008.
Since joining the Foreign Service in 1986, she has also served at posts in Canada, Russia, Somalia, and the United Kingdom.
Marie Yovanovitch received a B.A. from Princeton University and an M.S. from the National War College.
