Professor Millns's main research interests lie in the areas of European and comparative public law, constitutional law, human rights and feminist legal studies. She has published widely on issues of gender equality in Europe and much of her work offers a critical, feminist persepective on contemporary matters of public law.  


She is currently researching into the impact of Brexit for women and sexual minorities. This work will be published in a collection (edited by Prof Millns with Sussex colleagues Nuno Ferreira and Moira Dustin), Feminist and Queer Perspectives on Brexit, forthcoming with Palgrave in their series on gender and politics. She is also the guest editor of a special issue on Gender and Brexit for the European Journal of Politics and Gender to be published in summer 2019.


In addition to the work on Brexit, Professor Millns is currently carrying out research for a monograph on the gendered nature of the principle of respect for human dignity for publication in 2020. 


Professor Millns has completed a number of multi-partner research projects funded by the European Union, including the JURISTRAS project (2006-09), exploring from a comparative perspective, processes of human rights litigation in the European Court of Human Rights, together with their effects on national legislative reform and policy making in EU member states; and projects on 'The Future of Europe in an Age of Changes, Challenges and Chances' (2012/13) and 'Connecting with Citizens' (2013/14).
