Much of my work so far has dealt with mental representation. Our minds are composed of densely interwoven systems that enable perception, action, language, and conceptual thought. I have largely focused on exploring the plurality of these representational capacities and their relations to one another, drawing on research in psychology, neuroscience, linguistics, and anthropology.

Another strand of my research has to do with scientific representation. The sciences produce models of natural systems and phenomena that can be expressed in language, pictures, diagrams, graphs, and software. Understanding scientific representation requires seeing how models from different scientific domains can be integrated, and how they relate to the underlying structure of the world. These writings also touch on more general questions of scientific explanation.

Finally, the visual arts contain a rich variety of representational styles and practices. I have recently started working on questions about depiction and realism, relations between images and text, the limits of pictorial representation, and photography as an image-making practice.

In the future I hope to write on the history of the human sciences and the self.
