Manuel Kreutle was a member of the Program on Science and Global Security until June 2023. Prior to joining Princeton, he was a member of the Carl Friedrich von Weizsäcker-Centre for Science and Peace Research at the University of Hamburg, Germany, where he was working on nuclear disarmament verification, conducting neutron transport Monte Carlo simulations with Geant4 and co-organizing the multinational “NuDiVe” and “NuDiVe 2022” disarmament verification exercises. He holds a Bachelor of Science in Physics from the University of Heidelberg and a Master of Science from the University of Hamburg, both Germany.

Research Interests

One aspect of Manuel Kreutle’s work is the verification of a dismantlement of individual nuclear warheads by simulating scenarios that cover presence and absence measurements of nuclear material with the CERN-developed particle transport Monte Carlo code Geant4. This mostly covers neutron emission and its behavior under different shielding conditions. Another aspect of his work includes the gamification of nuclear disarmament verification concepts. Using tabletop games, role play games and virtual reality simulations he tests and improves verification procedures and tires to facilitate education and training. He also studies emerging technologies with the aim of extending the verification and monitoring toolkit.
