Threats to global health security continue to evolve due to the changing nature of conflict, advances in science and technology, globalization, and the growing threat posed by emerging infectious diseases and pandemics. Pandemics, Bioterrorism and Global Health Security: From Anthrax to Zika is a three-day, non-credit summer workshop designed to introduce participants to the challenges facing the world at the intersection of national security, public health, and the life sciences. The workshop faculty are internationally recognized experts from the government, private sector, and academia who have been extensively involved with research and policy-making on public health, biodefense, and national security issues. The workshop is organized by the Biodefense Graduate Program at the Schar School of Policy and Government.
