Chemical weapons are weapons that exploit the toxicity of chemicals to bring about death or harm. The toxic chemicals on which chemical weapons are based are known as chemical warfare agents.

The elimination of this entire category of weapons is the aim of the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction, also known as the Chemical Weapons Convention or CWC, administered by the Hague-based Organisation for the Prohibition of Chemical Weapons (OPCW).

Dr. Costanzi’s work contributes to strengthening the international system designed to counter the threat of chemical weapons. His research in this domain focuses on:

  • identifying gaps in current policies and practices that may enable the development or acquisition of chemical weapons; and,
  • conceptualizing and developing computational approaches and tools that help close those gaps and support global efforts to counter chemical weapons.
