James Lewis writes on technology and strategy at the Center for Strategic and International Studies (CSIS). Before joining CSIS, he was a diplomat and a member of the Senior Executive Service. Lewis has a track record of being among the first to identify new tech and security issues and devise polices to address them. He developed groundbreaking policies on cybersecurity, remote sensing, encryption, spectrum management, and high-tech exports to China, including 5G, software, and semiconductors. He also helped create the Wassenaar Arrangement. Lewis was a senior adviser for four UN Groups of Governmental Experts on Information Security, and his work on norms to build stability in cyberspace is foundational. He leads a long-running track 2 dialogue with the China Institutes of Contemporary International Relations. His current work looks at how countries innovate and at digitalization and its political, economic, and security effects. Early in his career, Lewis was a political adviser to two combatant commanders. Lewis has authored numerous publications since coming to CSIS (see the full list here). He is frequently quoted in the media, has served on several federal advisory committees, and has testified numerous times before Congress. He received his PhD from the University of Chicago.
