I am currently a Presidential Postdoctoral Fellow at Virginia Tech, working primarily under the supervision of Prof. Dawei Zhou, with co-advisors Prof. Lu Zhang and Prof. Le Wang. My research develops methods and agentic AI systems for reliable reasoning, evaluation, and decision-making with Large Language Models (LLMs), with an emphasis on understanding model behavior and improving interpretability, robustness, and controllability.

I received my Ph.D. from Stony Brook University, where I was advised by Prof. Susu Xu. Prior to that, I earned a Master of Science in Computer Science from Stevens Institute of Technology, where I worked with Prof. Xiaojiang Du, and a Bachelor of Science in Computer Science from Xi’an Jiaotong University. From 2024 to 2025, I was also a Graduate Visiting Scholar at Johns Hopkins University.

My research interests broadly lie in language and multimodal models, and agentic AI. My recent work focuses on:

  • Understanding and improving LLMs, through post-training, interpretable reasoning, and reliable evaluation (Mosaic-IT, RuleR, Epi2Diff, SciCore).

  • Multimodal understanding and reasoning, with an emphasis on grounding and trustworthy evaluation (TRIG, MusiXQA, CaughtCheating).

  • Agentic AI for real-world decision support, including disaster response, behavioral modeling, and infrastructure design (FLARE, SILIC, StreetDesigner).

I am also exploring reliable control in physical AI.

Across these directions, I aim to build AI systems that are not only capable, but also interpretable, controllable, and useful in settings where reliability matters. I welcome collaborations on trustworthy LLM systems, agentic workflows, and high-impact AI applications across academic and industry settings.

I'm looking forward to opportunities for collaboration across academia and industry.

Beyond Research

Outside of research, I enjoy working out 🏋️, cooking at home 👨‍🍳 (especially a good steak 🥩), and photography 📷.
I also love hiking 🥾, traveling ✈️, catching a musical 🎭, and exploring art in all its forms 🎨.

Right now, I’m especially looking forward to GTA VI .
I love exploring new places 🌍, trying new things ✨, and following my own path 🧭.
