WASHINGTON — President Barack Obama says he will nominate Aaron Williams, a career international development specialist, to be director of the Peace Corps.

Williams, vice president for international business development with RTI International, has helped design and manage assistance programs in Africa, Latin America, the Middle East and Asia. He was a senior manager at the U.S. Agency for International Development and reached the rank of career minister in the Senior Foreign Service.

If confirmed, Williams will fill a slot that has been occupied in an acting capacity by Jody K. Olsen, the Peace Corps' deputy director since 2002. Williams is a former Peace Corps volunteer, serving in the Dominican Republic in 1970-1971.
