Academic Profile

I joined the University of Sheffield as a Lecturer in Spanish Law in September 2013. I am originally from Spain, where I was trained as a lawyer and where I gained my PhD in Law and Political Science (Universidad Autónoma de Madrid). I carry out an interdisciplinary research in English and Spanish in the field of Law and Politics, focusing on European constitutional jurisdictions, Constitutional Politics and Regional Integration.

  • MA in Democracy and Government, Universidad Autónoma de Madrid (Spain)
  • LLB Law, Universidad de Almería (Spain)

Teaching and Learning

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.

The modules I teach are:

Undergraduate Postgraduate
Spanish Legal Language (Convenor) European Union Constitutional Law (Convenor)
Legal and Political Culture and the Spanish-Speaking World (Convenor)
European Union Law
Spanish Law and Legal System (Convenor)
Administrative Law and Justice
