Nasos Roussias received his Bachelors in Political Science & History from Panteion University, Athens, Greece, which was followed by an MA in Political Behaviour at the University of Essex. He then went to Yale University where he received an MA, MPhil and a PhD in Political Science.

After Yale he spent three years as a junior research at the Center for Advanced Study in the Social Sciences (CEACS), at the Juan March Foundation, Madrid, Spain. He joined the department of Politics at Sheffield, in 2011.

Nasos’s research touches on several topics related with elections, voters and parties. His PhD dissertation dealt with the consolidation process of party systems in new democracies around the world. The dissertation showed that for consolidation to occur, parties and voters need to go through a learning period which is strongly conditioned by the incentives imposed by the electoral system in place.

Apart from party system consolidation, he has several other projects investigating the effects of electoral manipulation on party systems, the effects of parliamentary representation on party success, the organization of parties, and electoral behaviour.

Research group

I am keen to supervise ambitious and motivated research students in a variety of areas, touching on elections, parties, voters and institutions. Topics, among other things, can include questions on:

  • Electoral Competition
  • Political Behaviour
  • Democratization
  • Electoral Fraud
  • Party Politics
  • Cross-national comparative research

I am currently supervising three dissertations, by Andrew Arnott, Andreas Dafnos and Norhafiza Mohd Hed. 

Teaching activities

I am currently teaching three modules. I am the module leader on  POL226 Comparative Politics, a second year course that touches on several key topics on Comparative Politics. I also lead a Level 3 module, POL3119 Party Politics, which provides an in-depth analysis of parties and party systems. At the Masters level I teach POL6150 Democratization, a module examining the various theoretical and empirical issues associated with transitions to democracy. 

I value teaching immensely; I consider it a privilege to be able to interact with students both inside and outside the classroom and I try to provide them with a teaching experience that enriches them as potential academics, but mostly as intelligent individuals. My teaching approach is one that stresses interactive learning, with students encouraged to participate not only in seminars but also in lectures. Using key academic contributions I aim at introducing students to important topics, while also exposing them to different approaches using cutting-edge methodological tools.

Above and beyond consuming the results of current research, students are pushed to develop critical thinking and challenge “stylized facts” and “conventional wisdoms”. The overall aim of my courses is to combine a comprehensive coverage of seminal contributions with the development of analytical skills that can be used both within and outside an academic environment.

Students are expected to do the readings assigned for each week, as well as to look for examples that will illuminate topics that may be hard to grasp abstractly. Specific theoretical as well as empirical questions are assigned for seminars, which force students to acquire an understanding of key concepts and debates, as well as reflect on how they can be applied to real world phenomena.

Students are expected to participate actively in seminars, which among other things may include engaging on group activities, and preparing presentations. Modules also entail essay assignments, that promote the development of analytical skills, and final exams, that operate as an incentive to review the topics covered in class and clarify key concepts.
