I’m a Director at ByteDance’s Seed Team, where we focus on developing foundation models for AI agents. Our research covers cutting-edge areas such as advanced reasoning, tool use, agent reinforcement learning, and beyond.
One of our key initiatives is building AI Scientists—intelligent agents designed to accelerate scientific discovery, with an emphasis on breakthroughs in artificial intelligence itself.
Previously, I briefly led the Search Modeling Team at TikTok, working on core search technologies including indexing, retrieval, relevance ranking, and content understanding.
Before joining TikTok, I was a researcher at Google Research, where I specialized in information retrieval, language modeling, and search advertising.
Our team conducts a broad range of internal research, spanning evaluation, data, pretraining, reinforcement learning, and more.
While much of our work is internal, we occasionally publish research in collaboration with interns and visiting researchers. Some recent publications include:
We're hiring research scientists and interns! If you're passionate about building the next generation of intelligent agents, we’d love to hear from you.
