I am a historian of science who specializes in the history of nuclear weapons. I have also published on the history of eugenics. At times, I have also been a web developer, database programmer, and graphics designer, and I have sought to integrate these digital practices into my research work and in the interest of broadening public understanding of both history and science.

My book, Restricted Data: The History of Nuclear Secrecy in the United States, is in production with the University of Chicago Press, and will be available in early 2021.
I have published numerous articles for both academic and general audiences. I maintain a list of my publications here. Most of my publications have been on the history of nuclear weapons, though I have also published one article in the history of eugenics. I occasionally write articles for The New Yorker's Elements blog as well as other popular venues. My work has been cited in the New York Times, The Atlantic, the History Channel, Fox News, and even The Daily Show, among other venues.I am also the author of Restricted Data: The Nuclear Secrecy Blog, and the creator of the NUKEMAP, a popular nuclear weapons effects simulator.

Personal site:



From 2011-2014, I was an Associate Historian (a postdoctoral position) at the Center for the History of Physics at the American Institute of Physics. For the year prior to that, I was a postdoctoral fellow at the Managing the Atom Project (MTA) and the International Security Program at the Belfer Center for Science and International Affairs, Harvard Kennedy School of Government, and a Lecturer in the Department of the History of Science at Harvard University. I maintain an affiliation with the MTA program as a Research Associate. I have also had a long association with the Program on Science, Technology, and Society (STS) at the Harvard Kennedy School, and have been their design coordinator for many years. I have taught at Harvard University, the Massachusetts Institute of Technology, and Georgetown University. As a graduate student I was the Edward Teller Graduate Fellow in Science and Security Studies for the Office of History and Heritage Resources at the U.S. Department of Energy.

Among my consulting experiences, I was the guest curator for the Intrepid Museum (New York, NY) for their exhibit A View from the Deep: The Submarine Growler & the Cold War. I was also the historical consultant for the WGN America/Lionsgate television show MANHATTAN. You can also watch me talking about the Trinity site on Episode 6 of the Netflix show CONNECTED (2020).
