Lauren Borja will be a MacArthur Nuclear Security Postdoctoral Fellow at the CISAC in 2019-2020, where her research will focus on the cyber insider threat to the U.S. nuclear arsenal. She is broadly interested in the effect of new technology on nuclear security issues, leveraging her technical skills as a scientist to inform and contribute to the issues in nuclear policy. She received her Ph.D. from the University of California, Berkeley, where she constructed an ultrafast laser apparatus for studying fundamental interactions inside semiconductor materials with unprecedented resolution. Lauren completed her Ph.D. in December 2016 and is currently a Simons Foundation Postdoctoral Research Fellow at the University of British Columbia, where she studies nuclear disarmament and risk. She has authored articles on the Nuclear Ban Treaty, nuclear false alarms, and cybersecurity risks in the nuclear arsenal that have appeared in the Vancouver Sun, American Physical Society’s Physics and Society newsletter, and Bulletin of the Atomic Scientists.
