I am now building something new to keep pace with the changing world. Through entrepreneurship, including ClawVoyage and Eurandel AI, I have used AI to help improve the lives of 30M+ people. I have had the privilege of witnessing the rise and fall of hundreds of fields and ideas across academia, industry, and the startup world. Previously, I earned a PhD in CS from UC Berkeley, where I was part of Berkeley Artificial Intelligence Research (BAIR) and worked on AI for audio, healthcare, and HCI. Over the past three years, I also worked full-time on Meta's LLaMA 3 and LLaMA 4 teams, contributing across the full stack.
(1) Forward problems for general intelligence modeling
I work to leverage intelligence in a data-driven manner.
(2) Inverse problems for intelligence modeling
I work to find intelligence in AI models, aiming to steer, predict, and understand it.
In the past, I was interested in and worked on:
(1) Human-AI collaboration and deployment in high-stakes healthcare settings
I built collaborative, deployed systems for precision and public health — speech and language disorders such as dyslexia and primary progressive aphasia, and population-level language screening.
(2) Human-centered speech AI systems
I built speech AI grounded in human cognition and physiology (perception, production, physics), keeping people in the loop through interactive labeling, feedback, and supervision.
News & Updates
Released the Eurandel AI preview: a multimodal agent towards an empathetic, personalized assistant for life. Currently in beta for healthcare and education, non-commercial testing only. Looking for all-purpose collaborators! eurandel.ai →
I launched ClawVoyage 🦞 as an OPC in China. Within six months, it reached 30M users 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 →
