Julien de Troullioud de Lanversin
Julien de Troullioud de Lanversin will be joining CISAC as a Stanton Postdoctoral Fellow. Julien is finishing his Ph.D. at Princeton University’s Program on Science and Global Security. He is interested in how to verify and reconstruct past fissile material production programs with scientific tools. To that end, he developed innovative methods that use isotopic analysis from nuclear reactors to gain information on their past operation (nuclear archeology) and designed an open source software that can compute the istopic composition of fissile materials from nuclear reactors. His current research looks at the various modalities of the production of plutonium and tritium in production reactors and how transparency on tritium could be used to improve estimates on plutonium stockpiles. Julien also studies security questions related to civil and military nuclear programs in Northeast Asia through the lens of fissile material, with a focus on China and North Korea. Julien visited the Institute of Nuclear and New Energy Technologies at Tsinghua University for one semester in 2018 to collaborate with Chinese experts on work related to nuclear engineering and arms control. Julien’s work on nuclear archaeology has been published in the Journal of Science and Global Security. He received his Diplôme d’Ingénieur (M.Sc. And B.Sc.Eng.) from Ecole Centrale de Marseille in 2014. The same year he also obtained a M.Sc. in Nuclear Science and Engineering from the University of Tsinghua where he was a recipient of the Chinese Government Scholarship. Julien speaks and uses Chinese in his research and is a native French speaker.
