Pablo Hernández Sau holds a degree in History from the  Universidad Autónoma de Madrid and a PhD in History and Civilization from the European University Institute in Florence, with the thesis “A ‘Global’ House? The Bouligny Family (1700–1800)”. Since 2025, he has been a Junta de Andalucía-2024 postdoctoral researcher at Pablo de Olavide University, where he is developing the RIBERAS project: Mobility and colonial rivers in Iberian empires in the early contemporary age (1750-1830). Previously, he was a Marie Sklodowska-Curie postdoctoral researcher at the Center for Humanities (CHAM) at Universidade NOVA in Lisbon. He has also been a Juan de la Cierva postdoctoral researcher at Pompeu Fabra University (2022–2024), as well as at the Madrid Institute for Advanced Studies (MIAS) at Casa de Velázquez (2021–2022) and at the University of Manchester (2020–2021).

Hernández Sau specializes in the history of mobility, transculturality, and global history in the Iberian worlds of the 18th century. His research focuses on experiences of displacement, negotiations of cultural and social diversity, and the political processes of Bourbon and Pombaline reformulation in the Spanish and Portuguese empires. In recent years, his work has focused on Louisiana, Mozambique, and the Mississippi and Zambezi valleys, where he is developing a new line of research on mobility policies in the revolutionary era and political ecology in colonial riverine contexts. As a result of this research, he has published articles in high-impact journals such as Historia Crítica, Mélanges de la Casa de Velázquez, and the Journal of Iberian & Latin American Studies, as well as book chapters and a monograph in preparation for Routledge (scheduled for 2026).
