My research and writing range over the last century and a variety of American topics from the history of engineering, the laboratory as a workplace, mathematical machinery and computers as cultural artifacts, and, most generally, the relationships between science, technology, and culture. As a teacher, I'm happiest in my introductory survey of science and technology in the western world and in upper-division and graduate seminars on comparative scientific traditions and on science and culture in the cold war. Recently, I’ve begun work on a book tentatively titled "The Rise and Fall of the Rocket State: Ballistic Culture in Cold War America."
