About
I work on AI strategy at ByteDance, with a focus on Seed. Previously, I was the founding product lead for Doubao. Before that, I worked at Microsoft. I graduated from UC Berkeley.
My current work brings together company-wide strategy and management research. I study how AI capabilities, training data, and evaluation shape long-term priorities, and how teams and organizations can best support those priorities.
Selected work
- Contextual assistance at Doubao. Work on “Ask Doubao”: bringing the right context into a conversation, investigating failure cases, and evaluating whether an answer actually helps.
- Documents as a workspace. Product work across Doubao’s AI reading and cloud-drive experiences, including source citations, document navigation, and ways to use files as context.
- AI for working with code. Product exploration for Doubao × MarsCode: helping developers understand unfamiliar repositories and move between reading, building, and troubleshooting.
- AI data and model strategy. Research into training-data suppliers, reinforcement-learning environments, evaluation, and the domains where better AI capabilities could matter most.
