I'm interested in research questions that will still matter five years from now.
I build interpretable, human-centered foundation models — and the systems and robots that bring them into the real world.
(1) Interpretable-by-design, mechanistically grounded foundation models
I develop foundation models whose internal representations are structured and inspectable, and whose reasoning, planning, and dynamics can be examined and controlled.
(2) Human-AI collaboration and deployment in high-stakes healthcare settings
I build collaborative, deployed systems for precision and public health — speech and language disorders such as dyslexia and primary progressive aphasia, and population-level language screening.
(3) Human-centered speech AI systems
I build speech AI that is grounded in human cognition and physiology (perception, production, physics) and that keeps people in the loop through interactive labeling, feedback, and supervision.
(4) Inverse problems for intelligence modeling
I work to find intelligence in AI models, aiming to steer, predict, and understand it.
News & Updates
I launched ClawVoyage 🦞 as an OPC in China. Within six months, it reached 10M users and ~$30M+ in transaction volume, and has since undergone a merger. I also received 50+ speaking invitations from Shenzhen’s 🦞 community. Stay tuned for what comes next!
We host the Bay Area Speech AI for Health, Education, and HCI Workshoptwice a year, connecting academia, industry, healthcare, education, and venture capital to advance human-centered speech intelligence. Join us to present, exchange ideas, or collaborate!
As approved by the California State Government, starting from 2025 public schools will adopt our language screener, where I developed the first and state-of-the-art speech dysfluency transcriber UDM / SSDM, serving 1 million kids! Read the report →
