My academic home is in the field of Science and Technology Studies (STS), and my interests are in the nature and use of expertise. This translates into questions about the sorts of knowledge needed to make decisions, who possesses it and how it is shared and acted upon.

Within STS, my work has played a central role in founding what has been called 'Studies of Expertise and Experience' or the 'Third Wave of Science Studies.' The characteristic features of this approach are a more 'realist' approach to expertise that emphasises the role of tacit knowledge and and the development of a more explicitly normative approach through which STS scholars can to contribute to technological decision-making in the public domain.
