Daniel Mack is a senior independent consultant with over 20 years of experience on issues of armed violence reduction and international arms control. Most recently, Daniel led a project for Global Rights Compliance on firearms exports to (and diversion within) Guatemala, focused on bolstering local civil society capacity to press for legal pathways to gun violence accountability and human rights due diligence. 

Daniel is Member of the Advisory Committee of Global Action on Gun Violence (GAGV), and is also a Senior Advisor at the NYU Center on International Cooperation, where for over two years he spearheaded the Pathfinders’ Halving Global Violence program, establishing and convening the HGV Task Force and providing strategic direction and leadership to the Peace in Our Cities and GENSAC networks. Prior to Pathfinders, Daniel worked for five years as an independent consultant, and provided research, policy or strategic advice for several United Nations agencies (UNIDIR, UNLIREC, UNODA, UNODC) and international NGOs, including Save the Children Norway, Small Arms Survey, Control Arms, Conectas Direitos Humanos (Brazil), PAX (Netherlands), and Asociación para Políticas Públicas (Argentina).

Earlier in his career, Daniel worked for nine years at the NGO Instituto Sou da Paz in São Paulo, Brazil, spearheading its arms control efforts both at the national level and at global fora. Moreover, he was co-chair of the Control Arms coalition that pushed for the UN Arms Trade Treaty and member of the International Advisory Council of the International Action Network on Small Arms (IANSA), among other leadership roles. Daniel was a founding member of the Editorial Team of the publication ATT Monitor. Previously, he was a Research Associate at the Inter-American Dialogue in Washington, DC.
