Researchers at the University of Wisconsin–Madison and Princeton University have published a study in Nature Communications that calls attention to a blind spot in nuclear nonproliferation: The Democratic Republic of the Congo (DRC) has exported thousands of metric tons of uranium, and there is no accounting for where it has gone.
In partnership with Lighthouse Reports and the Financial Times, UW–Madison nuclear engineering professor and nuclear security expert Sébastien Philippe and Ryan Manzuk, a geologist and research fellow in Philippe’s group and at Princeton, conducted the study using countrywide mineralization and geochemical data.

Dr. Kathryn Huff leads the Office of Nuclear Energy as the Assistant Secretary. Before joining the Department of Energy, she was a professor in the Department of Nuclear, Plasma, and Radiological Engineering at the University of Illinois at Urbana-Champaign, where she led the Advanced Reactors and Fuel Cycles Research Group. She was previously a postdoctoral fellow in both the Nuclear Science and Security Consortium and the Berkeley Institute for Data Science at the University of California - Berkeley. She received her Ph.D. in nuclear engineering from the University of Wisconsin-Madison in 2013 and her undergraduate degree in physics from the University of Chicago. Her research has focused on modeling and simulation of advanced nuclear reactors and fuel cycles.
