I hold a joint appointment between the Department of Politics & International Relations and the Oxford School of Global and Area Studies (OSGA), wherein I am based at the Latin American Centre. My research interests include democratisation, presidentialism, comparative political institutions (parties, legislatures, and elections) and the politics and government of Latin America, especially Brazil.
In 1990, I initiated the Brazilian Legislative Survey which I now co-direct with Cesar Zucco Jr of the Fundação Getúlio Vargas in Rio de Janeiro. With Paul Chaisty and Nic Cheeseman, I recently co-authored a book based on our multi-year, ESRC-funded research project on "Coalitional Presidentialism in Africa, Latin America and Postcommunist Europe: Dynamics of Executive-Legislative Relations in New Democracies." Some of the video podcasts from our project are available here.
From 2012-2014, I was the Director of Graduate Studies in Politics in DPIR. I have served as Treasurer of the Latin American Studies Association and as President of the Brazilian Studies Association. I am currently an associate editor of the Journal of Politics in Latin America. I serve on the editorial boards of Comparative Political Studies, Political Behavior, Latin American Politics and Society (USA), América Latina Hoy (Spain), Política y Gobierno (Mexico), and Dados (Brazil). I also convene the Visiting Parliamentary Fellowship at St Antony's, through which two members of the UK Parliament join the College each Hilary Term and organise a series of debates on public affairs.
In DPIR, I teach mainly on the MPhil Comparative Government. I teach and tutor for the core course in Year One, and also offer an option paper on Comparative Presidentialism in Year Two. I also supervise DPhil students working on these topics and on Latin American politics more generally.
