About Me

I am a final-year Ph.D. candidate in Computer Science at University of Illinois Urbana-Champaign, advised by Prof. Derek Hoiem.

I aim to build intelligent agents that plan under partial information, remember what matters, and draw on past experience to avoid repeating failures. More specifically:

• Closed-loop Planning: How can models make decisions under partial information? Each decision must build on past observations while shaping what comes next.

• Memory Representation: How can an agent compress its past into a compact, updatable state that preserves what matters and turns experience into reusable lessons?

• Experience Retrieval: How do we recall useful past experiences while filtering out distractions?

I'm seeking full-time opportunities starting Summer 2027. If you're interested in my research or would simply like to connect, feel free to email me!

ReToken: Improving Long-Context VLMs with Visual Retrieval Token

Yao Xiao, Reuben Tan, Zhen Zhu, Yuqun Wu, Jianfeng Gao, Derek Hoiem

NeurIPS, 2026.

[TL;DR]

Attention tells you where a VLM looks, so shouldn't it tell you which frames matter? It doesn't: the retrieval signal lives in the value space, and a single learned token is enough to read it out.

TMLR, 2025. J2C certification, also presented at NeurIPS 2026.

[TL;DR]

A simple, training-free approach to get region tokens directly comparable to text embeddings, achieving state-of-the-art zero-shot region-level understanding.
