Dr Hebatalla Taha joined the Nuclear Knowledges program in November 2018 as a postdoctoral researcher in the ERC funded NUCLEAR project on ‘governing nuclear weapons choices’, She focuses on the intellectual history of categories used to make sense of nuclear realities and possibilities in the Middle East in the post-Cold War context. Her broader research interests include political economy, anthropology of development, as well as peace, conflict, and insecurity. She specializes in the Middle East and North Africa, particularly Egypt and Palestine/Israel. Heba was previously an ACSS Postdoctoral Fellow at the American University of Beirut (January - September 2018) and has worked with the International Institute for Strategic Studies.

Dr Sébastien Philippe is a Stanton Nuclear Security Postdoctoral Fellow at Harvard Kennedy School’s Belfer Center. His research focuses on developing new verification technologies and approaches to support future nuclear arms control and disarmament efforts. In parallel, he pursues research interests on French nuclear policymaking as a visiting fellow with Sciences-Po Paris’ Nuclear Knowledges Program. Before joining Harvard, Philippe was a Research Associate with Princeton University’s Program on Science and Global Security. He earned his PhD in Mechanical and Aerospace Engineering from Princeton University and was recognized by the University as an Honorific Fellow for “outstanding performance and professional promise.” He also worked in the French Ministry of Defense, where he was a nuclear safety expert for the strategic nuclear forces.

Prof. Benoît Pelopidas (PhD) founded the program Nuclear Knowledges and holds the chair of excellence in security studies at CERI (Sciences Po). He is also an affiliate of the Center for International Security and Cooperation (CISAC) at Stanford University and has been a frequent visiting fellow at Princeton University’s Program on Science and Global Security.

In France, Nuclear Knowledges is the first scholarly research program on the nuclear phenomenon, which is fully independent and transparent on its funding sources. 

He has been awarded four international prizes for his research. In 2017, he has been awarded one of the most competitive EU grants: an ERC Starting Grant (1,5 million € over five years) on nuclear weapons choices.

He focuses on the construction of knowledge about nuclear weapons, their institutional, conceptual, imaginal and memorial underpinnings. Conceptually, he elaborates nuclear vulnerability beyond its material and strategic dimensions. Empirically, Benoit’s focus is on nuclear “close calls”, crisis management and French nuclear history.
Over the last seven years, he has been engaging with policymaking elites in the US and Europe as well as civil society groups to advocate innovative nuclear disarmament and arms control policies.

Since 2013, he has been coordinating a team of 13 international researchers to write the first global history of the so-called "Cuban Missile Crisis" based on primary sources worlwide, which revisits fundamental concepts of IR and security studies such as the nuclear revolution, power, sovereignty, neutrality and alliance dynamics. 

Dr Nari Shelekpayev has been a postdoctoral research fellow with the Nuclear Knowledges program since November 2018. Within the ERC funded project NUCLEAR on ‘governing nuclear weapons choices’, he will focus on the intellectual history of categories used to make sense of nuclear realities and possibilities in Russian and Chinese in the post-Cold War context. He specializes in the intellectual history, comparative history of empires in the 19th and 20th centuries, as well as Soviet and post-Soviet history.

He specializes in political psychology, comparative public opinion with extensive use of cross-national survey data, and statistical modeling. At CERI, he currently works on the planning and design of a survey on attitudes toward nuclear weapons in the European Union within the ANR Project “de la vulnérabilité politique à l’âge nucléaire”. From 2013 to 2015, he was a J. P. Lemann Fellow at the UCLA Center for Brazilian Studies. In 2016-17, he received a Dissertation Year Fellow.
