Professor de Londras’ work is fundamentally concerned with the role, impact and operation of constitutionalism and rights in 'complex' policy areas (i.e. areas in respect of which there are no 'right anwers'). In exploring these matters, her work concentrates broadly on  terrorism/security and the law, (comparative) constitutional law, human rights law, and gender and the law. Inevitably these themes sometimes overlap; much of her work on human rights law for example has taken place in, or develops further the work that Professor de Londras has done in, the security/counter-terrorism context. 

Prof. de Londras’ work strives to consider law in context, and almost always adopts a comparative approach drawing insights from comparative constitutional law in particular, but also international law and international human rights law. Professor de Londras’ research work has been funded by the European Commission FP7 fund, the British Academy, the Joseph Rowntree Charitable Trust, and under the auspices of an ERC grant held in the Israel Democracy Institute. In 2017 Professor de Londras was awarded the Philip Leverhulme Prize in Law, which is supporting her full-time research agenda from November 2018-2021.
