Graham Allison was Director of Harvard's Belfer Center for Science and International Affairs from 1995 until July 2017. Allison is a leading analyst of U.S. national security and defense policy with a special interest in nuclear weapons, terrorism, and decision-making. As Assistant Secretary of Defense in the first Clinton Administration, Dr. Allison received the Defense Department's highest civilian award, the Defense Medal for Distinguished Public Service, for "reshaping relations with Russia, Ukraine, Belarus, and Kazakhstan to reduce the former Soviet nuclear arsenal."

His latest book, Destined for War: Can America and China Escape Thucydides’s Trap?, was published by Houghton Mifflin Harcourt in May 2017 and quickly became a national bestseller.  His 2013 book, Lee Kuan Yew: The Grand Master’s Insights on China, the United States and the World (co-authored with Robert Blackwill), has been a bestseller in the U.S. and abroad.  Nuclear Terrorism: The Ultimate Preventable Catastrophe, now in its third printing, was selected by the New York Times as one of the "100 most notable books of 2004."  Dr. Allison's first book, Essence of Decision: Explaining the Cuban Missile Crisis (1971), was released in an updated and revised second edition (1999) and ranks among the all-time bestsellers with more than 450,000 copies in print.

As "Founding Dean" of the modern Kennedy School, under his leadership, from 1977 to 1989, a small, undefined program grew twenty-fold to become a major professional school of public policy and government.

​Dr. Allison was born and raised in Charlotte, North Carolina. He was educated at Davidson College; Harvard College (B.A., magna cum laude, in History); Oxford University (B.A. and M.A., First Class Honors in Philosophy, Politics, and Economics); and Harvard University (Ph.D. in Political Science).
