My research interests concern the processes of reform and centralization in the Arab provinces of the Ottoman Empire throughout the 19^th century (Egypt, Syria, Iraq, North Africa), from a cultural and social perspective. The central role of the press and associations in the emergence of a public space during the Arab Renaissance and the issues of education and citizenship in the colonial and post-colonial periods are central to my research.

At the same time, my work bears on the symmetrical processes of professionalization and the popularization of Islamic expertise in the 20^th century. More specifically, I am interested in the institutional and curricular development of mosque-universities such as al-Azhar, Zaytuna and Qarawiyyin, from the 18^th century until their nationalization in the 1960s, and also in the legacies and uses of Islamic historiography, philosophy and law in the contemporary period, particularly in nationalism and Islamism.

My current research aims to contribute to the cultural history of Arab nationalism and to define its key institutions: volunteer associations and secret societies; scouting movements; school textbooks.

I am a medical historian and specialize in Southeast Asia. I have been working for over 15 years on the development of health policy and practices from the 19^th century to the present, with a particular focus in recent years on the multiple "encounters" between Western (biomedicine) and so-called alternative and traditional forms of medicine. I am a determined advocate of a multidisciplinary, transnational approach, and recently developed projects and published on medications as a social object, immigrants' health practices and the identity of Vietnamese medicine.

I have held the Canada Research Chair in Healthcare Pluralism since 2007, and I work to improve our understanding of changes in health indicators in modern societies, over-medication and rejection of vaccination, as well as the enthusiasm for alternative medicine - all behaviours that are giving rise to increasing concern but also to different interpretations, which deserve to be revisited and examined from a historical perspective.

My research interests are as follows:

1. The history of the Soviet Union and the consequences of its dismantlement, in particular the history of science and intellectuals, the transformation of research systems and the de-modernization of post-Soviet societies and socio-economic polarization and other effects on societies outside the post-Soviet space. 
    
2. The contemporary history of Jews and the history of Zionism and the state of Israel, in particular the connections between the Zionist movement and the political right in the West, Jewish opposition to Zionism, the development of the Jewish identity since the turn of the 20^th century and the origins and spread of Christian Zionism.
    
3. Science and higher education as factors in international relations, in particular scientific exchanges, the internationalization of education and the role of scientists in international politics.

The themes of some recently completed and current theses and dissertations:

• History textbooks in three post-Soviet states
• The historiography of some Cold War conflicts
• Franco-Romanian relations: between tradition and necessity (1949-1974)
