St Antony's College

I am currently serving as Head of the Social Sciences Division. My underlying academic appointment is shared between the Department of Politics & International Relations and the Oxford School of Global and Area Studies  (OSGA), wherein I am attached to 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 BehaviorLatin American Politics and Society (USA), América Latina Hoy (Spain), Política y Gobierno (Mexico), and Dados (Brazil).
