I study people who historically have not been considered scientists or technologists but who have, nonetheless, produced and applied knowledge about the natural world. I am especially interested in the history of computing, mathematics, and gender. I am an Assistant Professor at Michigan State University, where I am jointly appointed in History, Philosophy, and Sociology of Science at Lyman Briggs College and in Social Relations and Policy at James Madison College. My current book  A People’s History of Computing is under contract with Harvard University Press. My next book will likely be a history of the (ridiculous) idea that girls can’t do math. My research has received recognition and support from, among others, the American Academy of Arts and Sciences, the Charles Babbage Institute for the History of Information Technology, and the IEEE.
