Upon approval by the Scientific Council, at the end of 2019, the IHC assembled a new Permanent External Scientific Advisory Committee (CEPAC), with four members, all associates of European academic institutions. The new CEPAC includes Ewa Domanska (Adam Mickiewicz University), Melanie Torrent (Université de Picardie Jules Verne), Stefan Berger (Ruhr-Universität Bochum), and Xosé Manoel Núñez Seixas (University of Santiago de Compostela).

Ewa Domanska is Visiting Professor at Stanford University (USA) and Full Professor at Adam Mickiewicz University, Poland, where she received her doctorate in 1995 with a thesis on historiography and the postmodern turn in the humanities. Her research interests are focused on historiography and theory of history, uses of the past and genocide studies.

Melanie Torrent is a Professor at the Université de Picardie Jules Verne, in France, having also lectured at the Université Paris Diderot (2006-2019) and a research fellow at the Institute of Commonwealth Studies, University of London (2013-1019). Her current research is centred on the impacts of the end of the Empire on British society, diplomatic networks and European construction, colonialism and anti-colonialism. She is a member of the editorial committee of The Round Table: The Commonwealth Journal of International Affairs.

Stefan Berger is the Director of the Institute for Social Movements at Ruhr-Universität Bochum, Germany, and professor of Social History at the same university. He received his doctorate from the University of Oxford in 1990, with a comparative analysis of the Labour Party and the SPD in the early 20th century. He is a specialist in comparative labour studies, nationalisms and national identities, historiography and theory of history, and history of industrial heritage.

Xosé Manoel Núñez Seixas is Full Professor of Contemporary History at the University of Santiago de Compostela and vice president of the Consello da Cultura Galega [Galician Culture Council]; between 2012 and 2018, he was also Full Professor of Contemporary History of Europe at Ludwig-Maximilians-Universität München, Germany. He received his PhD at the European University Institute, Florence. He specializes in the comparative study of European nationalisms, migratory studies and the cultural history of violence.

The CEPAC is written into the IHC Statutes and it is responsible for monitoring and advising the Institute on its research activities; it has a two-year mandate, that can be renewed.
