Callum McDougall

I'm Callum - I founded the ARENA program for technical AI safety upskilling, I've also worked on various open source mech interp things. I was in Anthropic's interp team for ~6 months (working on some of their recent papers) and I'm currently doing interp at DeepMind. I like mathematical art, running, climbing, and most importantly I hold a Guinness World Record for the largest number of clothespegs held in one hand at once (yep, really).
