Sulgiye Park is a Senior Scientist in the Global Security Program at the Union of Concerned Scientists.
Her work focuses on the front and back end of the nuclear fuel cycle, monitoring and verifying nuclear activities, and analyzing fissile nuclear materials stockpiles.
Before joining UCS, Dr. Park worked as a research scientist at the Stanford Doerr School of Sustainability, where she looked at rare-earth metal supply chain issues in the US. She was also a MacArthur and Stanton Nuclear Security Fellow at Stanford University’s Center for International Security and Cooperation (CISAC), where her research focused on: analyzing geological resources, including uranium and critical metal resources, in North Korea; and radioactive waste management. She published multiple papers on North Korea’s uranium mining and milling processes for disarmament and nonproliferation efforts.
Dr. Park Sulgiye holds a Ph.D. in n Geological Sciences from Stanford University, where her thesis work involved characterization of nuclear and earth materials under extreme conditions.
