My area of concentration within the field of art history is the history of photography. I studied modern art and photography at Princeton and was awarded a doctoral degree there in 1995. I then served ten years as a curator at the San Francisco Museum of Modern Art, where I organized traveling exhibitions on the work of Carleton Watkins and Lewis Carroll as well as projects investigating themes such as the snapshot. Prior to my arrival at Brown, I was director of the Center for Creative Photography and associate professor of art history at the University of Arizona in Tucson. My research examines fundamental questions about photographs as visual representations, and the complicated ways we respond to them.
