I'm joining UW–Madison Computer Sciences UW School of Computer, Data & Information Sciences as an assistant professor in fall 2026!! There, I'll continue working on language models, computational social science, & responsible AI. 🌲🧀🚣🏻‍♀️ Apply to be my PhD student! Before then, I'll postdoc for a year at another UW🏔️ -- UW NLP Allen School.

Agentic AI will transform every enterprise–but only if agents are trusted experts. The key: Evaluation & tuning on specialized, expert data. I’m excited to announce two new products to support this–Snorkel AI Evaluate & Expert Data-as-a-Service–along w/ our $100M Series D! ---

Scale alone is not enough for AI data. Quality and complexity are equally critical. Excited to support all of these for LLM developers with Snorkel AI Data-as-a-Service, and to share our new leaderboard! — Our decade-plus of research and work in AI data has a simple point:

🚨Test-time scaling for code has a MASSIVE scalability issue on the horizon: the time to verify a candidate. ✅ORMs are a scalable solution through a generate-prune-then-rank approach. ✅This can be 11.65x faster than the full verification while only being 8.33% less accurate

Very exciting work on using weak supervision for RL- closing the “generation-verification gap”!! Once again- principled approaches to labeling/data development are the keys!
