Previously, she was a Senior Scientist at the Union of Concerned Scientists, where she specialized in analyzing the nuclear fuel pathways of North Korea and China. She earned her Ph.D. in Geological Sciences from Stanford, focusing on the behavior of nuclear materials under extreme environments, and later conducted research at the Stanford Institute for Materials and Energy Sciences on fabricating nanodiamonds for technological applications. As both a Stanton Foundation and MacArthur Foundation Fellow at CISAC, her work encompassed geologic analysis of North Korea’s uranium and critical metal resources, regulatory frameworks for nuclear waste management, and the production and supply chains of rare-earth and other critical metals in the United States.
