Cascading Enrichment: Are Gas-Centrifuges Spinning the World?

Matthias Englert is a postdoctoral fellow at CISAC. Before joining CISAC in 2009, he was a researcher at the Interdisciplinary Research Group Science Technology and Security (IANUS) and a PhD student at the department of physics at Darmstadt University of Technology in Germany.

His major research interests include nonproliferation, disarmament, arms control, nuclear postures and warheads, fissile material and production technologies, the civil use of nuclear power and its role in future energy scenarios and the possibility of nuclear terrorism. His research during his stay at CISAC focuses primarily on the technology of gas centrifuges for uranium enrichment, the implications of their use for the nonproliferation regime, and on technical and political measures to manage proliferation risks.

Englert has participated in projects investigating technical aspects of the concept of proliferation resistance with topics including the conversion of research reactors, uranium enrichment with gas centrifuges, reducing plutonium stockpiles with reactor-based options,  spallation neutron sources and fusion power plants. Additional research topics have included fissile material stockpiles, fuel-cycles and accelerator driven systems.

Although a substantial part of his professional work recently has been technical he is equally interested in and actively studies the historical, social and political aspects of the use of nuclear technologies. Research interests include the dispute about Article IV of the NPT, the future development of the NPT regime, possibilities for a nuclear weapons-free world, preventive arms control, and the history and development of proliferation relevant programs. By studying contemporary theory in philosophy through the interaction of science, technology and society, Englert has acquired analytical tools to reflect on approaches describing or addressing the problem of ambivalent technology.

Englert is a vice speaker of the working group Physics and Disarmament of the German Physical Society (DPG) and a board member of the  German Research Association for Science, Disarmament and Security (FONAS).
