I am currently serving as Head of the Social Sciences Division. Since 2005, I have held 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.
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 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." 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 and Political Behavior.
