My research interests revolve around collaboration, in particular the role of technologies that organize and channel it. I explore the transformations brought about by the use of information and communication technologies in groups and organizations. I prefer to work on projects that bring together researchers from several disciplines. For instance, I am currently working with CIRST (Centre interuniversitaire de recherche sur la science et les technologies) researchers and with the Faculty of Environmental Design here at the Université de Montréal. I have a special interest in situations involving heterogeneous collaboration, where the participants are encouraged to share different types of expertise and viewpoints. My focus is on socio-technical innovation. At present this consists of a study of relationships and the circulation of knowledge between users and developers of Web 2.0 (participatory Web) technologies.
