Systems Resilience: A New Analytical Framework for Nonproliferation?

Nonproliferation efforts have traditionally focused on controlling supply of proliferation-relevant technology, expertise, and material. As barriers to diffusion of all three have been lowered, there is increased acknowledgement of the need to reduce demand for such weapons, and, in cases where efforts to prevent proliferation have failed, the need to develop effective international responses. However, with few exceptions, approaches to nonproliferation have not changed qualitatively in the last 40 years. This research explores the concept of resilience as understood for other complex interactive systems, extracts key features, and applies them to nonproliferation. In addition, it examines unintended consequences of traditional nonproliferation strategies and feedbacks among them.  Based on insights gained from this exercise, a new analytical framework for nonproliferation will be proposed.

Arian L. Pregenzer is a 2009-2010 CISAC visiting scholar and a Senior Scientist in the Global Security Program at Sandia National Laboratories in Albuquerque, New Mexico. She is responsible for initiating new programs in arms control and nonproliferation and for developing strategies for international engagement for multiple laboratory programs. In addition, she provides leadership for Sandia's efforts to integrate across nuclear weapons, arms control, and nonproliferation missions to effectively meet nuclear security challenges.

Most recently, Dr. Pregenzer has focused on near-term steps that can enhance nuclear security while advancing the goals of NPT Article VI. She is particularly interested in how international technical cooperation on topics such as verification methods for nuclear arms control, nuclear weapons security and accountability, and nuclear fuel cycle management can establish the technical basis for moving toward a world without nuclear weapons.

Dr. Pregenzer has bachelors' degrees in physics, mathematics, and philosophy from the University of New Mexico, and a Ph.D. in theoretical condensed matter physics from the University of California at San Diego. Prior to her career in international security, she worked at Sandia to develop lithium ion sources for particle-beam-driven inertial confinement fusion.
