Nikos Tsafos

Interim Director and Senior Fellow, Energy Security and Climate Change Program

Nikos Tsafos is an interim director and senior fellow with the Energy Security and Climate Change Program at the Center for Strategic and International Studies (CSIS). His research interests include natural gas, the geopolitics of energy, the future of mobility, and the energy transition more broadly, especially the interplay between energy consumption, economic growth, and greenhouse gas emissions. Nikos has advised companies and governments in over 30 countries on some of the world’s most complex energy projects, and his experience includes market analysis, strategy formulation, due diligence, and support for commercial negotiations and project development.
Nikos led PFC Energy's (now IHS Markit) global gas consulting practice and was responsible for the firm's research agenda on global gas. He then spent 3.5 years as a commercial adviser to the Alaska State Legislature, focused largely on the $43 billion Alaska liquefied natural gas project. He was also an adjunct lecturer for four years at the Johns Hopkins School of Advanced International Studies (SAIS), where he taught a graduate-level course on natural gas. Nikos has published extensively on natural gas, and on energy and economics more broadly. He is the author of Beyond Debt: The Greek Crisis in Context (2013); numerous articles in publications like Foreign Affairs, the National Interest, EURACTIV, the Australian Financial Review, and others; research reports and commentaries for CSIS, the German Marshall Fund of the United States, and the National Bureau of Asian Research. His views appear frequently in print media, including the Financial Times, the New York Times, Axios, Bloomberg, and elsewhere. Nikos is passionate about data analysis and visualization—and is forever honing his skills in R, Python, D3.js, HTML, CSS, and JavaScript. He holds a B.A. in international relations and economics, with a minor in statistics, from Boston University, and an M.A. in international relations from Johns Hopkins SAIS.
