His first book entitled Moral Movements and Foreign Policy was published by Cambridge University Press in July 2010. In his book, Busby seeks to explain why some countries are willing to take on new international commitments championed by principled advocacy groups and others are not. Substantively, he explores the politics of climate change, developing country debt relief, HIV/AIDS, and the International Criminal Court in selected country cases in the advanced industrialized world. His second book with Ethan Kapstein, AIDS Drugs for All: Social Movements and Market Transformations was also published by Cambridge University Press in September 2013. That book seeks to understand the conditions under which movements can transform markets, with lessons learned from the global AIDS treatment advocacy campaign.
Busby is the author of several studies on climate change, national security, and energy policy from the Council on Foreign Relations, the Brookings Institution, the German Marshall Fund, and the Center for a New American Security (CNAS). Busby is one of the lead researchers in the Strauss Center project on Climate Change and African Political Stability (CCAPS), a $7.6 million grant funded by the U.S. Department of Defense. He has also written on U.S.-China relations on climate change for CNAS and Resources for the Future.
Busby is a Life Member in the Council on Foreign Relations and a member of the International Institute for Strategic Studies. His works have appeared in International Security, International Studies Quarterly, Perspectives on Politics, Security Studies, among other publications. Busby served in the Peace Corps in Ecuador (1997-1999), worked in Nicaragua (Summer 1994, Spring 1996), and consulted for the Inter-American Development Bank (2000). Prior to working with the Peace Corps, he was a Marshall Scholar at the University of East Anglia (Norwich, England), where he completed a second B.A. (with Honors) in Development Studies (1993-1995). He completed his first B.A. (with Highest Distinction) at the University of North Carolina at Chapel Hill in Political Science and Biology.
