Assistant Administrator

William Hammink serves as Assistant to the Administrator in the Office of Afghanistan and Pakistan Affairs (OAPA) leading USAID’s assistance efforts for two of the Agency’s largest missions. A Career Minister in the Senior Foreign Service, Mr. Hammink joined OAPA after serving in USAID’s Bureau for Africa as the Senior Deputy Assistant Administrator.

From 2013 until 2015, Hammink served as Mission Director in Afghanistan, USAID’s largest mission. Hammink led the Mission during the country’s 2014 national presidential elections and pivotal political, security and economic transition at the drawdown of U.S. and NATO security forces.

As USAID Mission Director in India, from 2011 to 2013, Hammink oversaw an annual $109 million program and introduced a new model of development cooperation, in which U.S. assistance was a powerful catalyst in the creation of innovative alliances with Indian public and private partners. Hammink served as USAID Mission Director in Sudan from 2009 until 2011. USAID helped parties of the 2005 Comprehensive Peace Agreement implement many of the agreement’s provisions, including nationwide elections in April 2010—the first multiparty elections since 1986—and a peaceful, on-time referendum on South Sudan’s self-determination in January 2011.

Earlier, Hammink was deputy assistant administrator in the USAID Bureau for Economic Growth, Agriculture and Trade.  Appointed to this position in September 2007, he provided senior policy advisory and management services in agriculture, economic growth, development credit and education.  He also co-chaired a U.S. Government interagency food security task force and served as the USAID representative to the G-8 food security experts group.

Hammink managed more than $2 billion in U.S. food aid as director of the Office of Food for Peace, from 2006-2007, testifying before three U.S. congressional committees on reauthorization of the Farm Bill.  From 2003 to 2006, he was USAID Mission Director in Ethiopia, managing one of the largest USAID programs in sub-Saharan Africa.


Mr. Hammink received bachelor's and master's degrees from the University of Minnesota, and has served in nine posts on three continents: Afghanistan, India, Sudan, Swaziland, Senegal, Ethiopia, Madagascar, Russia and West Bank/Gaza.
