I joined the School of Law of the University of Sheffield in 2013 as a Lecturer, and in 2022 I was promoted to Senior Lecturer.

My research focuses on the role of judicial institutions in democratic systems and processes of regional integration (particularly the European Union). My work has been published in journals such as, inter alia, European Constitutional Law Review, European Political Science Review, and Comparative European Politics. I also have been cited in Amicus Curiae briefs submitted to the European Court of Human Rights, and featured or published in international media such as France 24, El País and EUObserver.

I am a Fellow of the Higher Education Academy (now Advance HE). I enjoy teaching and helping students grow academically through an interdisciplinary legal education. In my classes I value the diversity of viewpoints of students and I try to create a respectful and friendly learning environment for all.

Teaching interests

I know how important a high-quality teaching is for my students. I try to combine the teaching of core and basic contents of each subject with the explanation of latest developments in the field, so that students are aware of which are the main current social and academic debates.

In the Spanish law modules that I teach I reproduce the main patterns of Spanish academia so that students can get familiar with it, I stimulate debate in Spanish language and encourage participation.

My aim is to get the best from my students, and for that reason I take into account what their starting point is and what their personal and social constraints are.

Topics I am interested in teaching:

  • Constitutional Law
  • Spanish Law
  • EU Law
  • Law and Politics
