At Global Shield, we envision a world in which all governments have acted decisively to reduce and, where possible, eliminate global catastrophic risk. Our mission is to ensure countries around the world enact and effectively implement policies that reduce global catastrophic risk.

Our cofounders

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. Jared is also the President of the Action Fund on Technology and Emerging Risk, where he previously led advocacy for policies that led to the enactment of the Global Catastrophic Risk Management Act (GCRMA). He previously worked as an Analyst in Emergency Management and Homeland Security Policy at the U.S. Congressional Research Service, where he confidentially advised the U.S. Congress on a range of critical policy topics, including the authorization and use of the Defense Production Act and many emergency response programs of the Stafford Disaster Relief and Emergency Assistance Act. He holds a B.S. in Social Psychology and an M.P.P. with a special emphasis is humanitarian crisis management.

Rumtin Sepasspour

Director of Policy

Rumtin has had a successful 15-year career across policy, business and research. Most recently, Rumtin has been a researcher, adviser and public advocate for the ways governments can reduce existential and global catastrophic risk. Since 2021, he has been leading pragmatic and pioneering research in the field of GCR policy as an independent researcher. This work has included research on how governments can better understand and govern risk and on all-hazards policy approaches to GCR. 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. Prior to this, Rumtin had a successful career in the Australian Public Service as a policy officer in the Department of the Prime Minister and Cabinet and an intelligence analyst in Australia’s Department of Defence. He is a Research Affiliate of the Centre for the Study of Existential Risk at the University of Cambridge and a Visiting Fellow with the School of Regulation and Global Governance at the Australian National University.

Ariel Conn

Original cofounder

Ariel was a cofounder of Global Shield, and left in November 2023. Here is her statement explaining her decision: 

“For personal reasons, I have decided to step back in my role as cofounder to focus my attention on other priorities. I could not be more excited about Global Shield and its ambitious goal of all-hazards GCR policy being adopted around the world. I’m confident this organization will succeed, which is one of the things that actually makes it easier for me to step back: I know the world and our collective future is in good hands.”

Ariel previously founded Mag10 Consulting, which helps organizations communicate and advocate for science and technology. She led the IEEE-SA Research Group on Issues of Autonomy and AI for Defense Systems, where she led a group of experts to develop a more nuanced understanding of autonomous weapons technologies. She also cofounded TANGO Future. Her work covers a range of issues, including global diversity issues, autonomous weapons systems, AI ethics and policy, nuclear weapons, climate change, and other global catastrophic risks. She also seeks to bridge the communications and knowledge gaps between technical experts, policy makers, industry, and the public. At TANGO and now with Global Shield, her focus is on bringing more underrepresented voices to these discussions, in order to more successfully and equitably address many of the world’s biggest risks. She was formerly the Director of Communication and Outreach at the Future of Life Institute (FLI). She’s also previously worked with NASA, the Idaho National Laboratory, the National Energy Technology Laboratory, MIT, Virginia Tech, ALLFED, the Association for the Advancement of Artificial Intelligence, and the Global Challenges Foundation. She holds a B.A. in English, a B.S. in physics, and an M.S. in geophysics.
