A bit late to announce, but I’m excited to share that I'll be starting as an assistant professor at UMD CS @univofmaryland.bsky.social this August.
I'll be recruiting PhD students this upcoming cycle for fall 2026. (And if you're a UMD grad student, sign up for my fall seminar!)

Lots of progress in mech interp (MI) lately! But how can we measure when new mech interp methods yield real improvements over prior work?
We propose 😎 𝗠𝗜𝗕: a 𝗠echanistic 𝗜nterpretability 𝗕enchmark!

Checkout our new preprint/project which has been over a year in the making! This has been a very fun collaboration (and one of the biggest I've personally participated in).
@amuuueller.bsky.social @boknilev.bsky.social and other co-authors are around #ICLR2025 if you want to find out more. 😊
