His research interests lie at the intersection of the rise of digital publishing and the history of computing. His first book, Four Shades of Gray (MIT Press: 2022) focused on the rise of the Amazon Kindle platform and its impact on trade publishing.

He is currently working on a longer history of reading on-screens before the mainstream adoption of the Web.
