Roza Otunbayeva, Kyrgyzstan's former foreign minister, is leading the central Asian nation's interim government one day after a bloody uprising forced President Kurmanbek Bakiyev to flee the capital.
Mrs Otunbayeva, 59, was a one-time ally of Mr Bakiyev, and served in his cabinet following the 2005 "Tulip Revolution", which overthrew the government of Askar Akayev.
But the Moscow-educated diplomat later broke with Mr Bakiyev, joining the opposition Social Democratic Party.
Mrs Otunbayeva, who is viewed by many in the former Soviet republic as a moderate, is a fluent English speaker and former ambassador to both the United States and Britain.
She is married with two children and until Wednesday's violent events was an MP in the country's parliament for the opposition Social Democratic Party.
A former university professor who graduated from Moscow State University in the Soviet era, she is also an accomplished former diplomat.
After graduating in philosophy at Moscow State University, she entered politics and quickly rose up the Kyrgyz Communist party ranks.
She first served as the republic's foreign minister under the Soviet Union, then again for two stints in the 1990s after Kyrgyzstan became independent.
While Mr Bakiyev's relationship with the Kremlin was seen to be increasingly fragile, Mrs Otunbayeva is believed to have close ties to Moscow, which she thanked for its support in her first press conference as interim leader.
A liberal-leaning former ally of Mr Akayev, she also served as the country's UN envoy to Georgia during the 2003 Rose Revolution there.
But Mrs Otunbayeva broke with Mr Akayev in 2004 to join an opposition movement made up of former high-ranking establishment figures.
A year later in 2005, she tried to stand for parliamentary elections but officials refused to register her on a technicality. Mr Akayev's daughter, meanwhile, was running in the same district.
Her Fatherland, or Ata-Jurt party, with its trademark yellow ribbons, which she co-founded, was one of the main opposition groups behind the 2005 Tulip Revolution, which brought Mr Bakiyev to power.
Mrs Otunbayeva briefly went on to serve as acting foreign minister under Mr Bakiyev, but failed to gain approval from parliament deputies for the post.
She later became highly critical of Mr Bakiyev, saying that his government continued the corruption and nepotism of the previous president. In 2007, she became a deputy for the opposition Social Democratic party.
"They stole our revolution!," she told Russia's Interfax new agency in March this year.
Mrs Otunbayeva is widely viewed as having presidential ambitions. It is unclear whether she can pull this off, although there are few challengers on the Kyrgyz political scene with her stature.
A month old, but I thought it was interesting to learn more about her. Also mods, need a tag for Kyrgyzstan!
Edit: Here are two videos. The first profiles her back in 2008 while the other's an interview of her after the coup.
Edit 2: Here's another interview here.
