Research areas
International politics and regulation of weapons of mass destruction, with emphasis on nuclear weapons and fissile materials, and on problems in technological decision-making.
Initially trained as an electrical engineer, William Walker has been involved in the study of technological innovation, energy policy, military industries and international nuclear relations during his academic career. Over the past decade, he has become particularly well known for his work on international inventories of, and control over, plutonium and highly enriched uranium, the fissile materials used in nuclear weapons. Since 2001, his research has focused on how to conceptualise and respond to the problems that weapons of mass destruction pose for international order. He has also been examining the political and institutional processes by which complex technological decisions and paths become entrenched.
