Harry Krejsa is the Director of Studies, Washington Office, for the Carnegie Mellon Institute for Strategy & Technology (CMIST).

Harry joined Carnegie Mellon from the White House’s Office of the National Cyber Director where he oversaw cyber and technology strategy for domestic and international policy. While there Harry co-directed the development and rollout of the Biden-Harris Administration’s National Cybersecurity Strategy, led the establishment of national modern energy security priorities, and represented the US government in consultations with foreign partners and the global private sector.

Prior to joining the White House, Harry oversaw strategy and US-China competition for the Department of Defense’s cyber policy office, including the first Trump Administration's DoD Cyber Strategy and inaugural Cyber Posture Review. He developed initial military guidance for new offensive authorities to deter and disrupt adversary cyber campaigns, and negotiated numerous “Hunt Forward” joint operations with foreign militaries to root out malware on strategic systems. Upon leaving DoD in 2021Harry was awarded the Office of the Secretary of Defense Medal for Exceptional Public Service.

Harry also served as Director of the Integration Cell at the US Cyberspace Solarium Commission, where he led research on emerging technology trends and their implications for US government policy. He oversaw the Commission’s strategy and policy development on norms and values in technology design, artificial intelligence, election cybersecurity, and China’s influence over strategic technologies. Before joining government, Harry was a fellow at the Center for a New American Security where he researched US-China economic and technology competition, broader Indo-Pacific security strategy, and the interaction of foreign policy with economic trends in the United States.
