Bio

I am a Postdoctoral Fellow at Stanford’s Center for International Security and Cooperation. I have a Ph.D. in Applied Physics from the Department of Mechanical and Aerospace Engineering at Princeton University.

My research seeks to better understand the production of weapon-usable materials in countries with nuclear programs. To that end, I have developed innovative methods that use isotopic analysis from nuclear reactors to gain information on their past operation (nuclear archeology) and have designed an open-source software (ONIX) that can compute the isotopic composition of fissile materials from nuclear reactors. The end goal of this research is to improve estimates on current plutonium stockpiles as well as to advance our understanding of the potential trajectories of the nuclear programs of several countries. I apply my technical analysis to nuclear programs in Northeast Asia in order to improve nuclear non-proliferation and arms control policies in the region.

Having received a scientific education both in China and the U.S., I am also interested in analyzing how the rise of Chinese science affects international collaboration in science (such as the U.S.-China partnership) as well as its impact on the nuclear industry and on nuclear arms control.

My work has been published in the Journal of Science and Global Security and in the Annals of Nuclear Energy. I received my Diplôme d’Ingénieur (M.Sc. And B.Sc.Eng.) from Ecole Centrale de Marseille in 2011. After studying for three years in Beijing with a Chinese Government Scholarship, I obtained an M.Sc. in Nuclear Science and Engineering from Tsinghua University in 2014. I speak and use Chinese in my research, and I am a native French speaker.
