Callum Watson is the Survey's gender coordinator. He manages both gender-specific projects that explore linkages between arms control and the Women, Peace and Security agenda, as well as supporting gender mainstreaming in the Survey's work more broadly.

Before joining the Survey, Callum worked for the Gender and Security Division at DCAF—the Geneva Centre for Security Sector Governance. His work encompassed teaching gender in the military, addressing gender bias in the justice sector, researching men and masculinities, and exploring barriers to women's meaningful participation in UN peacekeeping operations. Prior to that, he worked for the Fukuyama Board of Education in Japan.

Callum holds a BSc in International Relations from the London School of Economics and Political Science and a Master in International Affairs from the Graduate Institute for International and Development Studies, Geneva.
