I was raised in a community that emphasized integrity and joined Anthropic because I wanted to ensure this critical moment in AI goes well for humanity.

I’m grateful to work somewhere that chose not to sacrifice principles for any amount of revenue, even amid enormous pressure.

PhD in Computer Science, University of California San Diego 🎓

My research focused on uncertainty and safety in AI systems, including

🤷‍♀️letting models say "I don't know" under uncertainty
🔎understanding and reducing hallucinations
🔁 methods for answering "how much will providing data X improve performance on Y?" at inference time

Many thanks to my advisor @berkustun, to my incredible research collaborators, and to my wonderful friends, husband and family. Getting a PhD while becoming a first-time parent is definitely a recipe for growth!

When RAG systems hallucinate, is the LLM misusing available information or is the retrieved context insufficient? In our #ICLR2025 paper, we introduce "sufficient context" to disentangle these failure modes. Work w J. Zhang, C.S. Ferng, @DaChengJuan1, @ankurtaly @CyrusRashtchian

Baby’s first ICLR! (And mine too!) He had plenty of constructive feedback for mom’s poster pitch

✅Easy: train a model to automate a routine task
❌Hard: ensure the model is accurate with minimal human oversight

In our latest #ICLR24, we introduce a modeling paradigm for this setting

Joint w @CharlieTMarx @berkustun
