🧐 About Me

I am an incoming CS PhD student (25 Fall) at Rutgers University, supervised by Prof. Ryan Tang. I have completed my master’s degree at Sensing IntelliGence and MAchine learning(SIGMA) Lab in Wuhan University, under the supervision of Prof. Zengmao Wang and Prof. Bo Du.

Previously, I was a research intern at RZ-Lab in Purdue University, advised by Prof. Ruqi Zhang. I was also fortunate to work with Prof. Lu Cheng, Prof. Bo Han and Jianing Zhu.

πŸ€”Research Interests:
My current research focus is to develop methodologies for trustworthy machine learning, particularly in reliability and its applications to boost the safety of large language models and address critical challenges in healthcare. Besides, I am also experienced in other fields of machine learning like active learning, and its applications to object detection and remote sensing.

If you share the same research interests with me and are intereted in these areas or my previous works, feel free to drop me an email or add my Wechat . I am always delighted for potential collaborations!

CoT-UQ: Improving Response-wise Uncertainty Quantification in LLMs with Chain-of-Thought

[Preprint, arXiv 2025]

Boxuan Zhang and Ruqi Zhang

TL;DR: Propose to quantify response-wise uncertainty by integrating LLMs’ inherent reasoning capabilities through Chain-of-Thought (CoT) into the UQ process.

Shakespearean Sparks: The Dance of Hallucination and Creativity in LLMs’ Decoding Layers

[Preprint, arXiv 2025]

Zicong He*, Boxuan Zhang*, and Lu Cheng

TL;DR: Given the philosophical nature of creativity, we propose a narrow definition tailored to LLMs and introduce an evaluation framework, HCL, which quantifies Hallucination and Creativity across different Layers of LLMs during decoding.
