I am a professor in the History Department at the University of California, Santa Barbara where I research, write, and teach about the histories of technology and science.

My personal (non-UCSB) web page is here…

I am not currently accepting new graduate students.

  • Science, technology, and the environment after 1945 (primarily US)
  • The intersections of art, technology, and science
  • Histories of computing

Recent & Current Things: My new book – titled README: A Bookish History of Computing from Electronic Brains to Everywhere Machines – appeared with The MIT Press in December 2025. In it, I take a selection of about a dozen books (some famous, others not) about computers and computing and use them to tell a larger story about the history of information technologies since 1945. At its heart is the question: how did computers become popular, popularized, and pervasive? README is, in other words, a book about books about computing.

I have two new projects underway. One of them, with funding from the Canadian Institute for Advanced Research, explores how space exploration, astronomy, and the environment intersected and coalesced in the 20th century around the rubric of “habitability.” I am especially interested in this topic as it makes connections between extreme life, natural and built environments, and exoplanets. 

I also have a new effort underway which looks at the idea of “mountain cultures” as they relate to outdoor recreation and natural history in the western United States. Linked to this is an examination of outdoor recreation, 1850-1950, as seen through the lens of natural history, technology, and the environment.

Books:

  • Rivers of Knowledge: Anglers, Naturalists, and Science Done Streamside (under contract with Yale University Press).

  • The Limits to Life: Historical Perspectives on Habitability from Our Planet to Other Worlds (edited collection under contract with the University of Pittsburgh Press).

Selected Articles:

My research informs my teaching. I offer a variety of undergraduate and graduate courses including:

  • Science and the Modern World (History 20)
  • Technology and the Modern World (History 22)
  • The Atomic Age (History 105A)
  • Histories of Information and Computing (106C)
  • Machines, People, and Politics: Histories of Modern Technologies (History 109T)

In addition, I teach some more specialized small-enrollment undergraduate courses as well as graduate readings and research seminars.
