Electoral politics in Thailand has been a major theme of my work since a PhD thesis which later became my first book, Chamlong Srimuang and the New Thai Politics (Hurst 1997). I have published on elections, political parties, constitution-drafting exercises, and attempts to reform the political system, including a landmark edited volume on the 1997 constitutional changes, Reforming Thai Politics (NIAS Press, 2002). I've also discussed questions of democracy in a number of articles.
