Join the L3 lab.

The L3 lab is recruiting PhD students to start in Fall 2024.

We seek students with a background in a technical area (e.g. computer science, mathematics, physics) and relevant research interests (e.g. machine learning, language models, reinforcement learning, proof assistants; check out our projects page). If you are unsure, please apply!

Please mention Sean Welleck as a potential advisor in your CMU School of Computer Science PhD application. The early deadline for PhD applications is Nov. 29, 2023 at 3 p.m. EST, and the final deadline is Dec. 13, 2023 3 p.m. EST [source].

Should I send an email?
