Meghan O'Sullivan

Nonprofit and media reports have questioned whether O'Sullivan's academic work has been shaped by conflicts of interest. O'Sullivan, a noted climate scholar, has sat on the board of global oil corporation Hess. At the Harvard Kennedy School, she leads the Geopolitics of Energy initiative. According to a 2021 investigative report from student group Fossil Fuel Divest Harvard on funding Harvard research, this initiative has received funding from BP, and took steps to cover up this fact after becoming aware of investigatory efforts into the initiative's funding sources.

O'Sullivan is also a One Young World Counsellor, speaking about "Peace & Conflict Resolution to a group of 1,300 young people in Dublin, Ireland in 2013. O'Sullivan is currently the Chairwoman of the North American branch of the Rockefeller Trilateral Commission.

She was an advisor to Mitt Romney during his 2012 presidential campaign. In 2013, O'Sullivan was a signatory to an amicus curiae brief submitted to the Supreme Court in support of same-sex marriage during the Hollingsworth v. Perry case. During 2013, she acted as Vice-Chair to Richard Haass at talks between the political parties in Northern Ireland.

On May 31, 2007, President Bush announced that O'Sullivan was returning to Baghdad: .mw-parser-output .templatequote{overflow:hidden;margin:1em 0;padding:0 40px}.mw-parser-output .templatequote .templatequotecite{line-height:1.5em;text-align:left;padding-left:1.6em;margin-top:0}

With Stephen Hadley, she is also credited as being one of the original advocates in the White House of the 2007 "surge" strategy. On September 15, 2007, she left the White House and began teaching at Harvard.

Following the 2003 invasion of Iraq, she volunteered for the Office for Reconstruction and Humanitarian Assistance under Jay Garner. Defense Secretary Donald Rumsfeld told Jay Garner that he could not keep her (or Tom Warrick) on in Iraq, though Rumsfeld later relented. She was an assistant to Paul Bremer in the Coalition Provisional Authority. Starting July 2004, she was Senior Director for Iraq and Afghanistan at the United States National Security Council. O'Sullivan's last position at the White House was as the Special Assistant to the President and Deputy National Security Advisor for Iraq and Afghanistan from October 2005 to September 2007 where she frequently communicated via telephone with Fort Leavenworth's General David Petraeus on a new military strategy for Iraq.

O'Sullivan was instrumental in the 2003 Invasion of Iraq. In April 2021, the Washington Post issued a correction to an op-ed by O'Sullivan after the original version failed to disclose her board membership at Raytheon Corp, one of the largest weapons manufacturers in the world.

Between November 2001 and March 2003, O'Sullivan served in the Office of Policy Planning at the State Department, where she assisted Colin Powell in developing the smart sanctions policy proposal.

O'Sullivan was an aide to Sen. Daniel Patrick Moynihan, and between 1998 and 2001 a fellow at the Brookings Institution under Richard N. Haass.

She received her bachelor's degree from Georgetown University in 1991. O'Sullivan later received her master's degree in economics and her D.Phil. in politics from the University of Oxford. Her doctoral dissertation was about the Sri Lankan Civil War.
