I am an historian of science and of nineteenth-century Europe — especially France and Britain. I study the ways in which print media — things like newspapers, journals, books, and card catalogues — have evolved in conjunction with changes in how experts and publics come to know things about the natural world, and in the criteria they use to trust the knowledge claims of others.

I am Assistant Professor of the History of Science at Harvard University. In Spring 2012, I was resident at the Max Planck Institute for the History of Science in Berlin. My dissertation, completed in 2010, was called "Broken Pieces of Fact: The Scientific Periodical and the Politics of Search in Nineteenth-Century France and Britain."

I am currently writing a book on the rise of the authoritative scientific journal during the nineteenth century. My other major project is a history of machineries of search. I have a long-standing interest in the life and work of the French mathematician and technocrat Henri Poincaré.
