Introduction

Laboratory's photo

We conduct research on core technologies for interpretable and trustworthy natural language processing. Going beyond the mechanistic interpretation of existing large language models, we aim to create new model architectures that combine high levels of language understanding and usability with mechanistic guarantees and explanations at different levels of abstraction for users with different needs, from non-technical end users to domain experts, engineers, and research scientists. Through both fundamental and applied research, and in close collaboration with industry partners in educational AI, we seek to extend the frontier of language processing toward systems that are powerful, transparent, reliable, and grounded in scientific understanding.
