She was assistant professor of earth science and international affairs at Georgia Tech from 2003-4. While at GMU, Macfarlane was a member of the
Blue Ribbon Commission on America's Nuclear Future from 2010 to 2012. When NRC commission chair
Gregory Jaczko was forced to step down As Chairman of the NRC, Macfarlane prioritized the lessons learned from the
North Anna and
Fukushima incidents, as well as improving the NRC's communication with public stakeholders and paying more attention to the back end of the fuel cycle in an era when more U.S. nuclear power plants were decommissioned than built. She also pushed to make the NRC a more family-friendly workplace. She had raised questions a decade earlier about the suitability of the
Yucca Mountain site for long-term geologic disposal of high-level nuclear waste. Supporters of Yucca Mountain expected her to stall licensing of Yucca Mountain, but she complied with a court order that ruled her predecessor's actions illegal and directed the NRC to continue its licensing review. Instead of completing her term at NRC, Macfarlane became the Director of the Institute for International Science and Technology Policy and a Professor of science policy and international affairs at
Elliott School of International Affairs at
George Washington University in December 2014. She has written 10+ articles for the
Bulletin of the Atomic Scientists. ==Views==
