I am the Professor of Cultural Information Science at the University of Amsterdam, but has spent most of his academic career teaching at the University of Cambridge. For over 40 years, the history, practice, theory, and performance of information, especially digital information, in cultural institutions and society, has been central to my scholarly work. I have been deeply embedded in research in the fields of museology, history and sociology of science, post-colonial studies and information studies in the United States, Canada, Australia, and Europe. My research builds on the programs of cultural knowledge with respect to appropriation, sovereignty and use. My research and work has focused on diverse topics, ranging from the first digital collection projects in museums and universities in the 1970s to the history of knowledge and its ontologies, to the more recent emergence of the Web and ubiquitous computing. My early career was in museums in the US and the UK, and I have worked as a consultant to museums and governmental organizations for over 35 years. My recent research has focused on local knowledge and emergent systems across incommensurable expert communities (indigenous and scientific), focusing on the study and development of open source, social and distributive systems that entitle key knowledge experts’ sovereignty over their cultural knowledge and cultural property. Recent publications have focused on the deep history of digitality as media. I am a Member of the Board of the Amsterdam School of Heritage, Memory and Material Culture.
