I am a researcher working on the safety, control, and efficacy of neural language systems. I tackle these problems by deeply understanding their internal mechanisms and their often-surprising generalization behaviors. Feel free to look me up on Google Scholar or Twitter, or take my CV. The materials from my natural language processing course, a version of Columbia Computer Science 4705, are public. I did my PhD research at Stanford Computer Science, as part of the NLP group. I'm grateful to have been co-advised by Chris Manning and Percy Liang, and to have been supported by an NSF Graduate Research Fellowship. Before that, I did my undergrad studies at Penn. © 2026 John Hewitt
