In 1994, Ladner was appointed president of, and professor of philosophy and religion at, American University in Washington D.C. His appointment is credited with bringing stability to the university after a period of turmoil and rapid turnover of presidents. During his tenure, the university experienced financial and academic growth, along with recognition as a leading international university, that partnered with and helped found new universities around the world. The main thrust of Ladner's leadership was defined in a "15 point plan" in 2001, which was approved by faculty, staff and the board. During his tenure as president at American University, Ladner chaired the board of
trustees of the
Consortium of Universities of the Washington Metropolitan Area, the Patriot League Council of Presidents, and served on numerous other boards and commissions including the
National Collegiate Athletic Association (NCAA), the
Washington Board of Trade, and the
Committee for Economic Development, and the Commission on International Education for the
American Council on Education. He was also a member of the
Commission on Federal Election Reform, co-chaired by
Jimmy Carter and
James Baker; the NCAA Presidential Task Force on the Future of Intercollegiate Athletics; and a United Nations Advisory Group member and manuscript reviewer for the ground-breaking
Arab Human Development Report of 2002. In 2003, Ladner fired Susan Clampitt as the head of university-owned radio station,
WAMU, due to donor and staff outrage at fiscal mismanagement of the
NPR affiliate. Clampitt later sued both Ladner and the university, claiming that Ladner had approved all of her financial decisions, which depleted a $4 million endowment for the station. The court of appeals subsequently denied Clampitt's employment-related claims.
Work abroad Ladner helped secure the release of individuals jailed for human rights protests and activities in the Palestinian Territories (West Bank) and Burma (Myanmar). Additionally, he led a series of face-to-face talks between Israeli and Palestinian leaders in Ramallah, Jerusalem, and Washington, D.C. in 2003 and 2004. In 2001, Ladner negotiated with the
Chinese government for the release of
Gao Zhan, after she was held while being charged as a spy for the United States. Later, it was discovered that Zhan was actually a spy for the People's Republic of China, and she was charged with tax fraud and espionage by the United States but charges were dismissed and she was placed in protective custody after she participated in a CIA operation. Under Ladner's leadership,
American University expanded its reach abroad after being selected as the primary contracting institution to develop and manage two new universities, on in the United Arab Emirates (
UAE) and the other in
Nigeria. The Nigerian university, originally known as ABTI-American University (AAUN) and now called the
American University of Nigeria (AUN), attracts students from all over
Africa and around the world seeking an American style education. Unlike most universities in the country, AAUN offers a four-year undergraduate degree program divided among two years of general study followed by two of concentrated study in a major. This differs from most Nigerian universities which follow the British model in which students take classes only in their major. In the UAE, American University established the
American University of Sharjah. ==Resignation from presidency of American University==
