Hello

I spend my time thinking about how to make powerful AI systems honest and aligned to human values. I work on things honesty training, dangerous capability evaluations, monitoring and control.

I was the Program Lead, and now teach at ARENA, a ML engineering program for upskilling people in doing technical AI safety work. Previously, I was the director of Cambridge AI Safety Hub, where I founded the research program MARS and led upskilling ML programs like CaMLAB. I have a MSc in machine learning from UCL and a BA Hons in psychology & neuroscience from the University of Cambridge.
