**Meghan L. O’Sullivan** is the Jeane Kirkpatrick Professor of the Practice of International Affairs and the Director of the Geopolitics of Energy Project at Harvard University’s Kennedy School. She is also the chair of the North American Group of the Trilateral Commission. Her third book, Windfall: How the New Energy Abundance Upends Global Politics and Strengthens America’s Power, was published by Simon & Schuster in September 2017. Dr. O’Sullivan has extensive experience in policy formulation and in negotiation. From July 2013 to December 2013, Professor O’Sullivan was the Vice Chair of the All Party Talks in Northern Ireland. These negotiations sought to resolve issues that have been persistent obstacles to achieving a more durable peace in Northern Ireland since the 1998 Good Friday Agreement. Between 2004 and 2007, she was special assistant to President George W. Bush and Deputy National Security Advisor for Iraq and Afghanistan during the last two years of her tenure. There, she helped run two strategic policy reviews: one on Afghanistan in the summer of 2006 and one on Iraq in late 2006 and early 2007, which led to the “surge” strategy. In her job at the National Security Council, Dr. O’Sullivan was responsible for building consensus around new policy directions in Iraq and Afghanistan, as well as overseeing their execution.
