Studies of Science and Technology. The empirical research conducted while at Berkeley also became her widely cited 1981 publication The Manufacture of Knowledge: An Essay on the Constructivist and Contextual Nature of Science. Knorr-Cetina also received her Habilitation in sociology at the University of Bielefeld in 1981, and served as Professor of Sociology at Bielefeld from 1983 to 2001. Her work in the social studies of science during these years culminated in her widely-cited book Epistemic Cultures: How the Sciences Make Knowledge, published in 1999. Knorr-Cetina's progression to understanding how technology mediates sociality led her to select global financial markets as a new "laboratory" to study knowledge in society. The first suggestion of this new field site was in the article "Sociality with objects: Social relations in postsocial knowledge societies" (1997), followed later by a conference on "The Status of the Object in Social Science" at Brunel University in September 1999. The paper she presented at this conference, entitled "The Market as an Object of Attachment: Exploring Postsocial Relations in Financial Markets", was later published in 2000. Her co-author was Urs Bruegger, a former foreign exchange dealer. The two collaborated on over a dozen articles on global financial markets. Sociology of global financial systems With the turn of the century, Knorr Cetina became interested in global financial markets as an object of study. From early work with Urs Bruegger, we see this developing into a strong research interest. This work is enhanced by the application of tools from science studies and the sociology of knowledge, for example, imagining "the market" as an object of attachment for traders or using market infrastructure (e.g. Bloomberg terminals) to see the microconstruction of the global market in the space of the local. The financial market infrastructure also comprises a "global scopic system" that integrates news and information across the world. The Synthetic Situation: Interactionism for a Global World Knorr Cetina’s lecture “The Synthetic Situation: Interactionism for a Global World” from 2008 is vital in rethinking past assumptions about communication and interaction order previously published by sociologists, namely Erving Goffman. In the lecture, which was eventually published in 2009, Knorr Cetina introduces and explains new concepts regarding global interaction. Although Goffman is widely published and read in these areas, much has changed since his day and Knorr Cetina conceptualized such changes. The introduction of the “synthetic situation” is arguably one of her most important new
