2023-2026
Senior Research Engineer, Google DeepMind
Worked on post-training for Gemini and on interpretability tools that are closer to production model work: probes, reward-model bias discovery, reasoning behavior, Gemma Scope, sparse autoencoders, model diffing, and steering.
Since MATS 6.0
MATS papers and mentoring
I have been a MATS mentor since MATS 6.0. MATS is the main way I mentor people; if you want to work with me, apply through MATS.
MATS usually runs winter and summer programs, so applications may not always be open.
2022-2023
Early mechanistic interpretability
Worked on circuits and automated circuit discovery, including IOI in GPT-2 Small and ACDC, before the later wave of large-scale SAE work.
