Who we are

We want to live in a world in which all countries around the world act individually and collaboratively to reduce the risk of global catastrophes.

Global Shield exists to advocate with governments worldwide to enact policies to better understand, prevent, prepare for, and respond to global catastrophic risk. We are building an international organization to educate and persuade  national and international policymakers to reduce global catastrophic risk (GCR). We believe an all-hazards policy approach to addressing GCR can ensure governments are managing global catastrophic risk more effectively.

We are the world’s first international advocacy organization devoted to all-hazard global catastrophic risk.

Jared Brown

Executive Director

Jared was previously the Director of U.S. and International Policy at the Future of Life Institute. At FLI, he focused on improving technology policy in the public and private sectors, particularly related to AI systems, to maximize the benefits of these technologies through the mitigation of their catastrophic risks. His work included active advocacy with U.S. and international policymakers and the provision of formal advice on draft and official policy. For example, Jared advised and advocated for better U.S. federal authorizations and funding for the safe and ethical research and development of emerging technologies, with multilateral government fora on the development of common guiding principles, with state legislatures on the procurement policies for artificial intelligence systems, with the European Union on the initial framing of the AI Act, and with industry on the creation and implementation of voluntary best practices. 

He has also worked on a wide range of issues at the intersection of policy and the management of U.S. homeland and national security risks. In his capacity as an Analyst in Emergency Management and Homeland Security Policy at the U.S. Congressional Research Service, he confidentially advised the U.S. Congress on a range of critical policy topics, including the authorization and use of the Defense Production Act, the emergency response and grant programs of the Stafford Disaster Relief and Emergency Assistance Act, the National Emergencies Act, among other topics. He began his career working on homeland security and emergency management policy at the U.S. Department of Transportation, where he also served as a member of the Emergency Support Function response team for numerous crises as part of the National Response Framework. He holds a B.S. in Social Psychology and an M.P.P. with a special emphasis is humanitarian crisis management.

He has contributed to the development of the GCR field of studies, through a report on the state of policy engagement by the field and databases to support research and engagement on policy. His publications include an essay on how intelligence communities can help reduce existential risk, a book chapter on existential AI risk, and op-eds on Australian policy towards nuclear risk and national risk.
