I am interested in how specific knowledge communities label and materially shape artistic and scientific objects in various contexts. People engage in rhetorical positioning through the creation of texts, making and unmaking the meanings of objects. Objects can be made to fit into the knowledge networks of science, art, or combinations of both. For different practitioners and audiences, what counts as art or science and their associations varies in interesting ways. My work has concerned a variety of objects, and in each case I am interested in situations that destabilize the categories of art and science.
