I'm nearly in Seoul for #CoRL2025, where I'll be presenting a talk on "Robots as the testbed for AI, AI as the testbed for Robots" at the Eval&Deploy workshop. Super excited to rep the newly formed Brown GIRAFFE Lab in the wild for the first time :D :D :D @confrobotlearning.bsky.social. Say hi!

The fun lil update is that this work won RLC Outstanding Paper in Emerging Topics :D. Work with Calarina Muslimani, Kerrick Johnstonbaugh, Suyog Chandramouli, @bradknox.bsky.social, and Matt Taylor.

Paper 2: reward design is hard, sure, but what about goal design? Surely that’s easier? Surely goals are prone to underspecification while rewards are prone to overspecificafion? Not so, at least not in our preliminary work. Specification design overall is hard!!!

Paper 1: reward design is really hard! So we introduce a method to take a small number of preferences and use those to compute a trajectory alignment coefficient metric, so that the reward designer can assess whether their reward function preserves their preference orderings.

I'll be presenting a position paper about consumer protection and AI in the US at ICML. I have a surprisingly optimistic take: our legal structures are stronger than I anticipated when I went to work on this issue in Congress.

Is everything broken rn? Yes. Will it stay broken? That's on us.

I'm terribly sad that my fellowship at
@simonsinstitute.bsky.social
is ending tomorrow. I've spent my time here mostly writing about, thinking about, and giving talks on my policy experiences in the US Senate, and to organize the Brown CNTR AI Policy Summer School (cntr.brown.edu/summer-school).

After 10 meandering days of driving and hiking across the country, we made it to Berkeley. Excited to call this place home for a few months :D
