) one of the definitive collections of conversation analytic studies - many of which have gone on to become classics in their own right. His own contribution to that book analysed the use of the particle 'oh' in conversation. This showed how 'oh' performed important conversational functions in displaying the speaker's change of state, from not knowing to knowing something. He has since followed up this study with work on 'oh' in response to assessment and as a preface to answering a question, as well as considering the implications of the study of 'oh' for understanding cognition.

In the late 1980s he was involved in a major study of the workings of political oratory. This identified a series of rhetorical formats which regularly led to applause in public settings.

In 1992 he co-edited (with Paul Drew) a volume that established the analysis of institutional talk as a central task for conversation analysis. The extended introduction laid out many of the central considerations that need to be addressed for an analysis of institutional talk to be successful. His chapter considered the way advice is delivered in health visitor interviews in the UK, and is a basic reference for subsequent studies of advice.

In the later 1990s he embarked on an extended programme of work on medical interaction. This had a number of strands, looking at the patterning of primary care visits, the way drugs such as antibiotics are prescribed, the way patients present their problems and how physicians deliver 'on-line' commentary on what they are doing.

Since 2000 he has been involved with influential work on questions in political press conferences (building on earlier work on the organization of news interviews more generally). A key work here is his joint book with Steve Clayman from UCLA, with whom he teaches the course 'Talk and Social Institutions' at UCLA.

More recent work has focused on the way epistemic issues - issues that relate to what speakers know and don't know - are managed in conversation. This brings together the concerns of conversation analyis with the concerns of discursive psychology
