Milton Leitenberg is a senior research associate at the Center for International and Security Studies at the University of Maryland (CISSM). His research is concentrated in three disparate areas of study: biological weapons; actual wars and conflicts of the past two decades and the issue of international intervention in these; and the history of nuclear weapons between the United States and Soviet Union and Russia between 1945 and 1995. CISSM published his major monograph, Biological Weapons Arms Control, in 1996. Since 1992, he has published over 30 papers in the area of biological weapons. Several of these papers concern the biowarfare program of the former Soviet Union, and The Soviet Biological Weapons Program: A History was published by Harvard University Press in 2013. Leitenberg published two other recent books on the subject of biological weapons: The Problem of Biological Weapons (National Defense College, Stockholm, 2004) and Assessing the Biological Weapons and Bioterrorism Threat (US Army War College, December 2005).
