Nancy Van House is concerned with people's information creation and use, and the interaction of information systems and technology with knowledge work. She uses the concepts and methods of STS to better understand knowledge work, knowledge communities, and technology development and use. Her current research is concerned with (1) the social uses of photography, and their relationship to the emerging uses of networked, digital imaging technology, and (2) trust and credibility in internet-based information, and the role of knowledge communities in shaping practices and warranting information. She combines approaches from new media, visual anthropology and sociology, visual culture, and human-computer interaction (HCI), and especially Science and Technology Studies (STS).
