Semi-presidential regimes and presidential activism

I am the principal investigator of Taming the presidents? Exploring the links between presidential activism, policy-making capacity, and regime legitimacy, a four-year project (2020-2024) funded by the Academy of Finland ( The project examines the links between presidential activism, policy-making capacity, and regime legitimacy. Drawing on top-level interviews, data on presidential behaviour, expert survey, and public opinion surveys, it asks what are the consequences of presidential activism for policy-making and the stability and legitimacy of political regimes. Institutionalized coordination mechanisms between the two executives should result in lower intra-executive conflict and thus higher policy-making capacity which in turn should produce stronger public trust in political institutions. Considering the challenges facing semi-presidential countries, particularly in Central and Eastern Europe, the lessons drawn from this project also benefit practitioners involved in questions of institutional design. The project employs doctoral researcher Maarika Kujanen and postdoctoral researcher Vesa Koskimaa. Collaborative partners are Anna Fruhstorfer (Freie Universität Berlin), Gianluca Passarelli (Sapienza University, Roma) and Thomas Sedelius (Högskolan Dalarna). Together with Sedelius we co-authored a book published by Palgrave, Semi-Presidential Policy-Making in Europe: Executive Coordination and Political Leadership (2020), which analysed coordination between the president and the government in Finland, Lithuania, and Romania (

Legislatures, ideologies, and foreign and security policy

Together with Wolfgang Wagner (VU Amsterdam, we study the role of national legislatures and political parties as well as the European Parliament in foreign and security policy. We co-edited a special issue of West European which analyzed legislative-executive relations in foreign affairs ( More recently we published a special issue for Foreign Policy Analysis which focuses on the role of political parties and ideologies in foreign and security policy (

Collaboration with Karl Magnus Johansson

I have known and collaborated with Karl Magnus Johansson (Södertörn University) ever since we met as doctoral students in the mid-1990s. Our respective dissertations focused on the European Parliament and the Europarties, and over the years we have co-authored various publications on the Europarties and on how EU impacts on the domestic politics of Sweden and Finland. In recent years we have also written several papers on government communication and I was glad to be part of an edited volume comparing government-media links in Finland, Lithuania, Poland, and Sweden. The book, titled Close and Distant: Political Executive–Media Relations in Four Countries, is available for free at

Publications in Finnish

I also believe in the value of producing scientific publications in Finnish. Throughout my career I have worked extensively with my Finnish colleagues, particularly co-editing various volumes on Finnish politics and the EU. All of these have been used as course material or exam books in Finnish higher education institutions. Juho Saari (Tampere University) and I have co-edited several books on European integration. The most recent ones are Reunalla vai ytimessä? Suomen EU-politiikan muutos ja jatkuvuus from 2017 which analyses Finnish EU policy (, and Moninaisuudessaan yhtenäinen? Euroopan unionin suunta from 2021, which focuses on the current challenges facing the EU (
