IT Editor, Software & Hardware
I’m MIT Technology Review’s IT editor for hardware and software and enjoy a diverse diet of algorithms, Internet, and human-computer interaction with chips on the side. Working in our San Francisco office, I cover new ideas about what computers can do for us, whether they spring from tech giants, new startups, or academic labs.
My journey to the West Coast started in a small English town called Wantage and took in the University of Cambridge, Imperial College London, and five years writing and editing technology news coverage at New Scientist magazine.
