Radosław (Radek) Sikorski, a senior fellow at the Center for European Studies at Harvard University, was formerly Poland's defense minister (2005–2007), foreign minister (2007–2014), and speaker of parliament (2014–2015).

Once a part of the Solidarity movement, he is a graduate of Oxford University, having earned his bachelor's and master's degrees in politics, philosophy, and economics (PPE). Radosław served as a war reporter in Afghanistan and Angola, and in 1988 he won the World Press Photo Contest for spot news. From 2001–2005, he was a resident scholar at the American Enterprise Institute in Washington.

As minister of foreign affairs, he was the Polish signatory of the Treaty of Lisbon in 2007. Together with Carl Bildt, he launched the EU's Eastern Partnership, and he proposed and helped establish the European Endowment for Democracy. Radosław negotiated and signed the Poland-Russia regional visa- free regime, the Poland-US missile defense agreement, and, together with the foreign ministers of Germany and France, the accord between the pro-EU opposition and Ukrainian President Viktor Yanukovych in 2013. In 2012, Foreign Policy named Radosław one of its 100 global thinkers for “telling the truth even when it's not diplomatic.”
