Professor Ashiagbor’s research is united by an interest in bridging social science-influenced legal scholarship around labour and migration, the European Union and regionalism, equality, governance and economic law, with historical and humanities-inflected legal scholarship around race and colonialism. 

She has long worked within the socio-legal tradition, beginning with her doctorate (European University Institute, 2002) and prize-winning monograph (Oxford University Press, 2005) which drew together law, governance, and the economics of labour market regulation in the European Union. Her publications made an early contribution to debates around ‘new forms of governance’ within the EU, and are now at the forefront of examining the contribution of ‘economic sociology of law’ for the understanding of national, European and transnational labour law regimes. 

Recent research explores European integration, in particular in the creation of the single market and the social dimension of that market, through the lens of European colonialism. Diamond’s current research project, for which she was awarded a British Academy/Leverhulme Trust Senior Research Fellowship in 2023, is on Reconceptualising Labour Law: Race, Legal Form and the Legacies of Colonialism. This research is influenced by ongoing collaborations with , University of Toronto. Diamond’s 2021 article ‘’, has become one of the most highly read articles published in the Industrial Law Journal, the leading English-language labour law journal globally.

Professor Ashiagbor’s academic work has received funding from a number of sources: she has been the recipient of the US-EU Fulbright Research Scholarship; a Fernand Braudel Senior Fellowship; a Leverhulme Trust Research Fellowship; and a British Academy Senior Research Fellowship. In October 2020, she was made Fellow of the Academy of Social Sciences (FAcSS), for her contribution to social science.
