Christine Wormuth, undersecretary for policy at the Defense Department, will leave her current position in June after more than seven years of service under the current administration.
Defense Secretary Ashton Carter said in a statement released Friday that Wormuth will be replaced by Brian McKeon, principal deputy defense undersecretary for policy, on an interim basis.
David Shear, assistant defense secretary for Asian and Pacific security affairs, will take over as principal deputy defense undersecretary for policy.
“[Wormuth] has devoted herself to enhancing America’s national security,” Carter said.
The Senate confirmed Wormuth to her current role in June 2014.
Prior to her current position, she served as deputy defense undersecretary for strategy, plans and force development.
Her other government roles include senior director for defense policy and strategy on the National Security Staff and principal deputy assistant defense secretary for homeland defense and Americas’ security affairs under the office of the defense undersecretary for policy.
Wormuth also served at the Center for Strategic and International Studies as a senior fellow in the international security program and at the Independent Commission on the Security Forces of Iraq as a staff director.
She also worked as a principal at defense consulting firm DFI Government Services.
