Curriculum vitae

Greetings! I’m Bruce, a Ph.D. student at the UCLA HCI lab advised by Professor Xiang ‘Anthony’ Chen.

I’m a human-AI researcher building the future forms of LLMs and AI agents that understand more deeply, interact more naturally, and align more seamlessly with humans. For example, interfaces where users can steer AI’s thoughts mid-conversation (ThinkaloudLM), agents that proactively engage in group conversations by modeling intrinsic motivation (Inner Thoughts), and multimodal agents that adapts to and stays in sync with real-world constraints (Human I/O).

My work has been recognized and supported by an Amazon Ph.D. Fellowship, an ACM UIST Best Paper Award 🏆, two ACM CHI Best Paper Honorable Mentions 🏅, an ED Rice Outstanding Master Student Award 🎓 , and a Distinguished Master’s Thesis Research Award 🎓 at UCLA. I also held research internships at Google, Meta Reality Labs and Snap Research.
