Ambassador Princeton Lyman, President Obama's former Special Envoy for Sudan and South Sudan, has joined the US Institute of Peace (USIP) as a Senior Advisor.
USIP Press published Lyman’s book on South Africa’s transition from apartheid to democracy, Partner to History: The U.S. Role in South Africa's Transition to Democracy, in 2002. He was also a Senior Fellow at USIP from 1999 to 2000.
Lyman has previously worked as the Ralph Bunche Chair for Africa policy studies at the Council on Foreign Relations (CFR), and as Executive Director of the Global Interdependence Initiative at the Aspen Institute.
USIP was recently ranked as the 18th best think tank in the US by the University of Pennsylvania annual think tank rankings.
Here is a previous Think Tank Watch post (which is periodically updated) on Obama Administration officials who have stepped down and entered the think tank world.
