The Obama administration’s top government contracting official is stepping down to join academia.

Daniel I. Gordon, who has served as head of the Office of Federal Procurement Policy since 2009, is to serve as associate dean for government contracting law at the George Washington University Law School, a new position for the school.

In announcing his departure, the White House noted that spending on government contracting has dropped for the first time in more than a dozen years. The administration has put an emphasis on reducing the number of no-bid contracts, canceling large information technology contracts and forcing federal agencies to buy office supplies and other services in bulk instead of as separate customers.

He also pushed proposals that would require businesses to disclose their political activity when applying for government contracts — a controversial move blasted by congressional Republicans as unfriendly to the business community.

In a blog post announcing Gordon’s departure, Office of Management and Budget Director Jacob J. Lew said “We will continue to build on his important work to make sure our procurement system delivers for the American taxpayers, so that the progress he has helped bring about will continue to be felt well beyond his departure from federal service.”

Before joining the Obama administration, Gordon served as a contracting specialist and general counsel at the Government Accountability Office.
